            Colors with MasterColorPicker

            MasterColorPicker uses a color-specification based loosely on the CSS4 specs. It will always output colors according to those specs, with a few exceptions that can be activated using “options”:

            • It can define colors using some color-spaces that CSS does not recognize.
            • It can define “hue angles” using units and/or symbols that CSS does not recognize.
            • It can output more “named colors” than the basic CSS list of colors.
            • It can add non-standard Alpha (opacity) values to “named” colors.

            Valid values for color inputs are similar to “loose” CSS specifications and include:

            • RGB values in 6-digit hexadecimal (hex) with or without the leading # symbol.
            • RGB values as:
              • integer byte values (0—255)
              • percent ratios (0%—100% – be sure to use the percent % symbol)

              Each value may be separated by spaces/commas.  You may mix byte and percent values in the same spec.  You may wrap() or prefix: the values with rgb( ) or rgb: but that is not necessary.

            • various different color-space models including:
              • CMYK
              • CMY
              • HSV / HSB
              • HSL
              • HCG
              • HWB
              • Hue ←  define only a hue-angle-value and see the full-color (fully chromatic) tone of the hue.
              • XYZ →  (Observer = 2°, Illuminant = D65) 0 ≤ X ≤ 95.047, 0 ≤ Y ≤ 100, 0 ≤ Z ≤ 108.883

              Use models by wrapping() or prefixing: their given values.  Each value may be separated by spaces/commas.  Values are given as percent ratios (0%—100% with or without the percent sign %); except Hue values are given in angular values (starting at 3:00 and going counter-clockwise) using one of the following units: (the default unit used when none is specified is found on the MasterColorPicker “options” panel)

              • in degrees (0°—360° ← postfixed using the ° symbol or “deg”).
              • in radians (0ᴿ—2π≈6.28319ᴿ ← postfixed using the ᴿ symbol, the symbol, or “rad”).
              • in gradians (0ᵍ—400ᵍ ← postfixed using the symbol or “grad”).
              • in % of a turn (0%—100% ← postfixed using the % symbol).
              • of a turn (0●—1● ← postfixed using the symbol or “turn”).
              • The “degrees” ° symbol may be entered by typing SHIFT+CTRL+5%
              • The “radians” symbol may be entered by typing ALT+C
              • The “radians” ᴿ symbol may be entered by typing ALT+R
              • The “gradians” symbol may be entered by typing ALT+G
              • The “turn” symbol may be entered by typing CTRL+1!
            • Any of the available “named-colors” found in the color-table-palettes.  Colors should be prefixed: or wrapped() with the appropriate color-table-palette name.  CSS is the “default” palette and its colors do not need to be prefixed or wrapped.  Hackers can change the default palette thought the value at: SoftMoon.defaultPalette

            Alpha (opacity):

            You may specify opacity (the opposite of transparency) in any of the color space models (RGB, CMYK, CMY, HSV, HSL, HCG, HWB, Hue) by adding an additional factor (0-1) or percent (0%-100% ← you must use the percent % sign).  The color-space model names may or may not end with an additional “A” (for example, RGB vs. RGBA). Per CSS4 specifications, the opacity value may also be separated with a / symbol that is itself preceded and followed by a space; for example RGBA(0, 153, 255 / 62%)  Note the “loose” interpretation of CSS specs allows commas with the / alpha separator. Hex-RGB values may have an additional 2 hex digits to specify the alpha; for example #ADDCAD80 Named colors may use the same Alpha specification for color space models described above, but it must end with either a semicolin ; or a space followed by opacity;  For examples:
            DodgerBlue, 78%;
            ANSI: 35 / .84 opacity;

            • These all give the same red color:
              • 255 0 0
              • rgb (255 0 0)
              • rgb(255, 0, 0)
              • #FF0000

            Keyboard shortcuts:

            These are defined for a QUERTY keyboard; other keyboards may be similar.  Hackers can redefine these keys:  MasterColorPicker.panelTabKey  and  MasterColorPicker.panelBacktabKey  if their keyboard normally generates different characters than > and < when the CTRL key is pressed.

            Note browsers usually keep (SHIFT)?+CTRL+TAB and F7 for themselves, but if not…you can use them!  See also the Hue-Angle Symbols shortcuts above.

            Tab to the first input box in the top panel or next panel.
            Tab to the first input box in the bottom panel or previous panel.
            Shows the ☺Help☺ panel, or hides it when pressed with the SHIFT key.
            Shows the MyPalette panel, or hides it when pressed with the SHIFT key.  If there is a valid color in the input-box with keyboard-focus, pressing CTRL+F2 copies that color to the next open MyPalette entry.  If keyboard-focus is within MyPalette (you are typing in colors or their names, etc.), pressing CTRL+F2 creates a new sub-palette.
            Shows the Color-Space Lab panel, or hides it when pressed with the SHIFT key.  If there is a valid color in the input-box, pressing CTRL+F3 syncs the Color-Space Lab with that color.
            Shows the Color Thesaurus panel, or hides it when pressed with the SHIFT key.  (usually is availavble even if F7 is not)
            Shows the Color Thesaurus panel, or hides it when pressed with the SHIFT key.  (this is the typical key for a thesaurus in many aplications)
            If there is a valid color in the input-box, pressing CTRL+F7 syncs the Thesaurus with that color.

            Using MyPalette

            You can use the “MyPalette” interface to create your own Color Palette Tables, give each color a descriptive name if you choose (i.e. what you use it for in your project) organize them into sub-palettes and give each sub-palette a descriptive name, and save the Palette Table in various formats.  You can then later reload your saved Palette Table back into the “MyPalette” interface, or as a standard MasterColorPicker™ “color-picker table” Palette (automatically if you like).  This allows you to create projects that use the same color-set in many different images (for logos and product branding, etc.), as well as having a reference to the colors used in a design/image for later editing.  If you plan on creating final bit-map images with high-compression using a paletted-image format (such as .png), you can begin by creating and saving your palette of choice colors using MasterColorPicker’s™ MyPalette.

            When you save the palette you create, your colors and sub-palettes can be named or not or a mix, and if named it must have unique name in the “main palette” or “sub-palette” it is in, among “color names” and “sub-palette names”.  Names that are duplicates will be (depending on options set) either:

            • automatically appended with an index number,
            • overwritten by colors later in the palette with the same name;
            • or you will be notified of the conflict.

            Palette and Sub-palette names may not contain the :( characters, as these are used to distinguish the palette name from the color/subpalette name in the palette.  Color names may contain any characters, but two “hacks” are possible. First, you could name a color foo: bar, and if, in the same palette, there is a subpalette named foo with a color named bar it will never be found.  Also, because of how MasterColorPicker interprets “add-on” Alpha (opacity) values when working with named colors, a color named foo 30%; will be interpreted as a color named “foo” and then try to add a 30% opacity to the color-value if it finds said color.

            When the palette you create is loaded as a MasterColorPicker™ Palette Table, colors that you leave un-named will show in the table with the color-definition next to the color-swatch; whereas colors that you do name show up in the table with the name next to the color swatch, and the color definition will pop-up when the mouse-pointer hovers over the swatch.

            Alternative color names

            Alternative spellings for color names can be included, but hidden when listed as a MasterColorPicker Palette Table.  You do this by choosing lowercase or UPPERCASE for “Alternatives” in the Export File dialog.  Then colors you name with all lowercase or UPPERCASE letters (based on your choice) become “alternatives”.  For instance, the CSS Palette includes both “Gray” and “GREY” but only “Gray” shows in the table; yet the user can type Grey or gray (note color-names are also case-insensitive) and expect the same color. 

            Saving/Exporting your Palettes

            You can save the Palettes you create in various formats at various locations.  Each format has a different use and each location has its benefits and drawbacks.

            The browser’s private storage

            When you don't have access to a friendly server, the browser’s private storage can be the option that gives you the fastest, easiest workflow for current projects, as it will allow you to save MyPalette files and have them “autoload” as a MasterColorPicker™ Palette Table.  Each browser has a private storage “sandbox” that is unique for each “website” and/or each HTML page.  The JavaScript™ code can not store or access data outside the sandbox, and the data stored is not accessable by any other website, nor, generally speaking, is it readily accessable by the user of the browser outside of using the website (it will be on your storage drive somewhere so hacks are possible).  MasterColorPicker™ uses the JavaScript™ IndexedDB database interface to store your MyPalette files.  The “sandboxed” ►storage has a limit that should, under most circumstances, handle all of your files.  However, you should be aware that the broswer may delete them at any time, and that you may delete them at any time through the browser’s interface as described in the above link.  For that reason, you should save your Palette files in another more permenant location for long-term storage.

            Storage in a “localhost” server or a server “in the cloud”

            This requires that you (or your friends) have control of the server and requires the included color_palettes/index.php file or a similarly functioning file in another language (it’s a simple short file to translate).  A “localhost” server (a private server on your own computer) will offer you the most flexibility and convenience when saving/storing your MyPalette files, while a “shared central hub” server (possibly “in the cloud”) works great for teams that need to share files.

            Local file system storage

            You can always store your MyPalette files in any folder on your computer; however, this is the only option where MasterColorPicker™ does not have direct access to the file (JavaScript in a browser never has direct access to your file system) so it can not be simply autoloaded — you must manually add links to the HTML file containing MasterColorPicker™ — see below … … …

            Auto-loading your palettes

            If you save your palette to your “localhost” server, the server cloud, or in the browser’s private storage (when available), it can be auto-loaded in the future when you use MasterColorPicker™.  Simply select that option when you save your palette, and that’s it.

            If you are using MasterColorPicker™—desktop with the file:// protocol (you click on the MasterColorPicker_desktop.html file in your file system, for example), save the Palette file as type .js and save the file in the same folder as the MasterColorPicker_desktop.html file or in a sub-folder, or the browser will prevent you from loading it.  Then open the MasterColorPicker_desktop.html file in your favorite text-editor and scroll down about a page or so to the bottom of the HTML document head (see the line with: </head> just above the line with: <body> ).  Just above the bottom of the head you will see multiple lines that begin with <script type="… … … — duplicate one of them and change the src="… … …" so its filepath leads to the file you saved from “MyPalette.”  If it is in the same folder as MasterColorPicker_desktop.html you only need the filename: for example src="your_colors.palette.js"  If it is in a sub-folder, only include that subpath and filename: for example
            If you are using a Windows® system, don’t confuse folder seperators!  Browsers like forward-slashes / 
            Then save the MasterColorPicker_desktop.html file.

            Exporting to CSS files

            When you export your palette to a CSS file, the Palette & Sub-Palette names and Color names take on a special meaning:  they become CSS selectors.  Color names may also instead become CSS variables.  When you save the file, the export dialog offers an option to automatically convert the Color names into a variable or a type of CSS selector, or simply let you manage all that by hand.  If any of your names begin with a valid CSS selector, it will be recognized and and the name will not be auto-converted.  If you begin a name with the $ character, the $ will be removed from the beginning of the name, and the name will not then be auto-converted;  this is a “custom-selector” for an element-name, or any other special selector that may emerge.

            When MyPalette then exports to a CSS file, the (Sub-)Palette names chain together according to their “parent Palette” and recursively its “parent Palette” to create one long CSS selector.  (Note that MyPalette does not validate your CSS, it only chains together what you create.)  If any of your Color names are — or are automatically converted to — a CSS selector, then it is appended to the selector chain of the palette it is in, and the color it defined is set as a “color: ” property/value pair for that appended chain’s resulting CSS selector.  If your Color name begins with ¡bg! (use SHIFT+CTRL+1! for the ¡ character) then it is stripped from the beginning of your colorname and the above said property/value pair is instead a “background-color: ”.  If your Color name begins with ! then it is stripped from the beginning of your colorname and the above said property/value pair is marked as “!important”.  Use ¡bg!! to do both.  For example, if your Palette name is “body” and a Sub-Palette name is “div.foobar” and a Color name in the “div.foobar” Sub-Palette is “¡bg!!warning” and “auto-convert” is set for “classes”, and the color you define is “#401000” then the output line in the CSS file would be: body div.foobar .warning { background-color: #401000 !important; }

            If your Color name is — or is automatically converted to — a CSS variable (it begins with --) then it is assigned as a property/value pair to the selector defined by the (Sub-)Palette name and its hierarchy.  Similarly, if a color has no name (after processing out “background-color” and “!important” markers) then it is assigned as a property/value pair (including its background and important properties) to the selector defined by the (Sub-)Palette name and its hierarchy.  Given the example in the above paragraph, if the Color name is simply ¡bg!! then the output is: body div.foobar { background-color: #401000 !important; } and if another Color name in the same Sub-Palette is --bazbuz with the color-definition #1000A0 then the output is: body div.foobar { background-color: #401000 !important; --bazbuz: #1000A0; }

            Using the PaletteManager

            The PaletteManager will help you keep track of Palette files you save to your browser’s private storage DataBase as well as files you save to a server.  This is the only way you can manage your browser’s private storage without hacking your browser’s filesystem — or simply deleting all stored data through your browser’s “options” menu.  For a remote server, this gives you an opportunity to manage the files directly without having to pester Eugene in the I.T. department.

            Most functions are self-evident; to rename a file, you can:  •double-click, or •shift-click, or •right-click (the “menu click”), or when using browsers for big boys & girls (here’s winkin’ at ►you, Apple®!) from the MasterColorPicker color-input textbox (with the PaletteManager panel open), press SHIFT+CTRL+.> until focus is within the PaletteManager panel, then press TAB until focus is on the file you want to rename, then you can •double-press ENTER or •use SHIFT+ENTER or •use the “menu” key (looks kinda like this: ) when present.

            BeezEye Color Picker
            Classic color-wheel shows HSL, HSB-HSV, HCG, and CMYK color-spaces (one at a time) with user-controlled Lightness/Brightness-Value/Gray/Black.
            Simple² Color Picker
            Works with the HSL and HSB-HSV color-spaces (both at once) to bring you simple access to the tints/tones/shades of any color (hue) from the “pure” (fully chromatic) color to →black, →white, and →gray.
            YinYang NíHóng Color Picker
            Another classic style, delivers all of the 11,777,216 colors your 24-bit monitor can show within two easy clicks using either the HSL, HSB-HSV or HCG color-spaces.

            All these graphical color pickers, except for the YinYang NíHóng color picker, are designed to show colors in definite “steps” of progression, allowing you to easily work with gradients (see our Rainbow-Maker projects) and find “matching” colors from other hues/tints/tones/shades.  The number of steps, or variety of colors, is user-controllable in real-time, from just a few to “high resolution”.  Plus! MasterColorPicker brings you these additional features:

            The MyPalette interface
            allows users to build their own color-table-palettes, give each color a descriptive name, organize them to your liking, group them into sub-palettes, and save/retrieve them for future use or export them to CSS & GIMP palette files, allowing complete and simple management of all colors used throughout an entire project.  ¡Plus! the colorblind-assistant included within helps you select colors for your project that work for everyone.
            The Color-Space Lab
            gives you direct control of, and displays a color’s definitive values in the RGB, HSV/HSB, HSL, HCG, HWB, & CMYK color-spaces.  It also allows you to add an Alpha (opacity) value to your selected color, automatically if you choose.  It can update automatically as you hover over a color in a palette; or you can use it to manually make color-space conversions.
            The Color Thesaurus
            shows you the nearest “named color” in any one of the named-color-table-palettes that you choose.
            The Gradientor
            (Under Construction) gives you measured color-stops in a gradient, so you can change the opacity at regular intervals when building complex translucent background or fill gradients; or to style individual elements (perhaps each element in a list, headlines, whatever) for a decorative gradient transitional effect.
            And much more… … …

            Now these ain’t your grandpa’s color pickers, mind you.  The MasterColorPicker project relies on a modern computer with a modern browser.  Browsers used must embrace “modern” standards in the year 2022.  Also, MasterColorPicker was designed as a professional’s tool, not a toy to be used on an ity-bity laptop, or other portable device with a small monitor.  While most of MasterColorPicker’s panels adjust to the monitor height, the Color-Space Lab is (for now at least) a fixed size, and can be trouble to drag and move on a smaller browser window.  A wide screen is also preferable when multiple panels are open at once.  But some smaller monitors may still be manageable.

            file:// vs. http://

            MasterColorPicker automatically adapts to the environment that it is used in.  It can be placed in a folder on your personal computer and loaded into a browser using the file:// protocol (you click on the file in your filesystem for example); or it can be placed on a server and loaded into a browser using the http:// or https:// protocol.  The server may be remote, public or private (in “the cloud” or in a private network); or be a localhost/ on your personal computer.  Both protocols offer similar functionality, but server-based usage is much more convenient if you plan on adding or deleting named-color database tables on a regular basis.  With server-based (http:// or https:// protocol) usage, you simply create the named-color database file and add it to the proper folder; that’s it.  Or you can use the MyPalette interface to create your named-color-table and save your file to the server, and not even worry about which folders where … or about the file formatting details … MasterColorPicker takes care of it all for you and even lets you autoload them in the future.  Simply remove your database file from the folder when you are done with it.  With file:// protocol usage, you must manually add and remove links to each of the named-color tables if you want them to auto-load when MasterColorPicker starts.  You can find info on doing such in MasterColorPicker’s ☺Help☺ panel while it is up-and-running. Both file:// and http:// (& https://) protocol usages allow you to create, save & load MyPalette and other named-color-table-palette files to & from your computer’s local filesystem, or the borwser’s private storeage database, so without a server you are not high-and-dry; the advantage of server usage is the simplified autoload feature, and having a centralized project host center for multiple developers. 

            You will find these two (2) files in the root folder that are tools for digital media developers to find the colors of their dream’s desire: MasterColorPicker_desktop.html and MasterColorPicker_desktop.php
            With the .html file, no server is needed; just click on the file and it will open in your browser.  With the .php file you of course need a server with PHP installed, and the same desktop tool is available, but it is an example of how you can incorporate MasterColorPicker into your own web page, and also of the subtle differences in the CSS and how the palette files are loaded (no HTML <script> tags needed to load them).  ¡Note both files support being used with a server!  There are two simple, primary differences between the files:  First, the .html file adds hardcoded links to the named-color-table files; (¡note both files recognize the environment they are active in, and if served from a server (via http:// or https://) the .html file will still allow you save & load palette files to/from the server-host!)  Second, the .html file adds a copy of some of the CSS styling directly into the HTML markup, which is needed for MasterColorPicker to work, since, for security reasons, browsers prevent a web page from reading any other files loaded from the local file system, including its own CSS stylesheet file (unless the user selects them by hand).

            The named-colors database files themselves need to be adapted to the protocol they are used in.  With server based (http:// or https:// protocol) usage, these files are JSON formatted, and loaded using JavaScript to make HTTP calls back to the server (think ajax); whereas with file:// protocol usage, they are themselves JavaScript files loaded with an HTML <script src='colors-filename.palette.js'> tag.  Without a server, the palette files need to be hard-coded into the web page.  However, the server can tell MasterColorPicker what files are available and MasterColorPicker can load what it wants.  Look at the difference in the two MasterColorPicker_desktop files for an example of this principle.  See also the file color_palettes/index.php and note that it is a relatively simple file that can be replaced with one in another programming language (Node.js, Perl, etc.); using a server with MasterColorPicker is not limited to one with PHP installed.  Except for the “demo” MasterColorPicker_desktop.php file, the palette index file is the only active file on the server (except for some “utility files” that are not technically part of the project and are not required), and even it can be replaced with a simple .txt file.

            Named-color tables

            Because the named-color database tables are required to be in only slightly different formats, and many of the files are very long, these database files only come packaged in one format: for file:// protocol usage (extention .js).  There is an included PHP powered converter which will convert all the files to the server (http:// or https:// protocol) usage format (extention .json).  There is also an instruction file which explains the details on how to do this using the included converter, and also how to do this by hand (which is remarkably simple) if you don't have PHP installed.  These two files, convert_palette_formats.php and converting_palette_formats.odt,  can be found in the color_palettes/ folder.

            Building your own named-color-tables by hand is simple to do using any basic text-editor.  If you have a list/database of colors, they can easily be incorporated into MasterColorPicker.  Complete instructions on how to do this can be found in the README.odt file in the color_palettes folder.  However, MasterColorPicker’s MyPalette interface makes creating them from scratch a snap!

            Using MasterColorPicker in your own project

            It’s very easy to incorporate MasterColorPicker into your own project.  To limit download size, but maximize ease of use, the MasterColorPicker package comes with only the _desktoptool” file.  Simply “cut out” the proper section of HTML from the MasterColorPicker_desktop.html file (the file is commented so you can tell what to cut), and either make it a new file: color-pickers/SoftMoon-WebWare/MasterColorPicker.htm that you can load into your webpage, for example using <?php include "color-pickers/SoftMoon-WebWare/MasterColorPicker.htm"; ?> in your web-page document at the appropriate place;  or simply paste the MasterColorPicker HTML you cut-out into your own web-page file; either way you then incorporate the MaterColorPicker HTML at whatever place in your document you desire.

            Take a look at the “demo” MasterColorPicker_desktop.php file and note that it “includes” the color-pickers/SoftMoon-WebWare/MasterColorPicker.htm file, and how the required JavaScript and CSS files are loaded.  Note that if you want your webpage to be loadable from the local filesystem using the file:// protocol (you click on the file in your filesystem for example), you must also include links to the named-color-table palette files (see the MasterColorPicker_desktop.html file for that example).  To actually make the “demo” MasterColorPicker_desktop.php file function as the MasterColorPicker tool, you will need to “cut-out” the proper section of HTML from the MasterColorPicker_desktop.html file as described above, just as you would for your own web-page.  This is to avoid duplication in the package to limit download size.

            Link the main MasterColorPicker.css file in the head of your document if you plan on using it.  Note how if you want your web-page to be able to be loaded in a browser with the URL using the file:// protocol (you click on the file in your filesystem for example), you must include a <style id='MasterColorPicker_desktop_stylesheet'> tag directly in the HTML page (¡not linked!) that includes the well-documented snippet of CSS found at the end of the similar <style> tag in the <head> of the MasterColorPicker_desktop.html file.  This is because the stylesheet must be modified directly in real-time by JavaScript, and browsers block JavaScript from reading files linked or loaded from the local file-system unless the end-user specifically selects that file by hand.

            Your HTML (web page) file must be encoded in UTF-8.  You should already be using this encoding in all your web page files anyway.  JavaScript is required to be encoded in UTF-8, and this project uses a character set beyond the standard ASCII characters.  Remember, UTF-8 is the #1 international choice for character encoding.

            Using the Picker interface

            MasterColorPicker is built on an instance of SoftMoon-WebWare’s Picker interface, which creates a new input “type:” picker.  Using this interface is easy.  The most simple way to use this project is to place anywhere within your document any number of <input type='MasterColorPicker' /> tags and/or <input type='text' pickerType='MasterColorPicker' /> tags.  The MasterColorPicker will find them when the document is fully loaded and automatically “register them,” i.e. add the necessary event-handlers to interface with the Picker.  Using <input type='color' pickerType='MasterColorPicker' /> tags can work with the MasterColorPicker also, and with browsers that already support this natively, you will get the native color-picker plus the MasterColorPicker;  but caution:  the W3C specs say that <input type='color' /> should limit the user’s input to basic ways of defining colors, which means that your MasterColorPicker implementation should limit its output to hexadecimal RGB with a leading # symbol.

            If you don’t like non-standard tag attributes, or you otherwise want to link an input tag to the MasterColorPicker, after the MasterColorPicker.js file is loaded, you can use JavaScript to link the input tag something like this:

            <script type='text/javascript'> myInput=document.getElementById('myMasterColorPickerInput'); MasterColorPicker.registerTargetElement(myInput); </script>

            A registered target element activates the Picker when the user clicks on it, or it otherwise receives “focus”. 

            Using the “color swatches”

            When a color is clicked on, the target element’s value is changed to the color-value-text.  Also, the associated “color swatch” has its background-color changed to the user-selected color, while its foreground-color becomes either black or white, opposing the background-color’s brightness.  The “color swatch” is either the target element itself when MasterColorPicker.showSwatchAs='background', or when MasterColorPicker.showSwatchAs='swatch' the color swatch is determined by the first valid condition in this list:

            1. If the target is as such: <input swatchId='myDocumentId' /> then the swatch is a document element with an id that matches “myDocumentId” if it exists.
            2. If the target-object has a JavaScript property “swatch,” then the swatch is that property’s value.
            3. If the JavaScript Object property is set, then the swatch is that property’s value.
            4. The document Element that follows the target-input.

            Be sure to read the end of the file MasterColorPicker.js for more details on using the “color swatch”.

            Targets other than text <input>s.

            You don’t need to use an <input type='text' /> with MasterColorPicker.  <textarea>s, <select>s, <input type='text' list='datalistID' />s, and even document text-nodes are automatically recognized by the MasterColorPicker.pick() method.  By default, the JavaScript value of MasterColorPicker.dataTarget.value is set when a color is picked.  If no dataTarget is set then the MasterColorPicker.masterTarget is used, if any.  The dataTarget and masterTarget each may be any JavaScript Object.  Or they may be <input type='hidden'> if you don't care to show the user the dirty color-code, but want to send the value back to the server with a form-submittal.  To supplement this functionality, add a JavaScript function to the Array of MasterColorPicker.pickFilters.  To replace this functionality, replace the MasterColorPicker.pick method with your own function.  See the file JS_toolbox/SoftMoon-WebWare/Picker.js for more details.

            MasterColorPicker’s file system structure.

            The MasterColorPicker JavaScript codebase does not rely on any particular file-system structure or filenames, ¡except! for the color_palettes/ folder and its index.… file when using http:// or https:// protocol to load your web-page (i.e. it is loaded from a server).  As noted above, the included index.php file may be replaced by another index.… file in another programming language or even a simple text file, but it must be named “index” for the server to automatically find it.  The color_palettes/ folder may be renamed if need be; however, you must then modify the value SoftMoon.colorPalettes_defaultPath either directly (¡before the color-palettes load!) or by modifying the file JS_toolbucket/SoftMoon-WebWare/RGB_Calc.js (at the file’s beginning).  The color_palettes/html-indexer.php file is optional, but its name also must remain unchanged.  It will allow end-users the ability to get an HTML-based index with hyperlinks of the color_palettes/ folder and its sub-folders by simply typing something like: in their browser’s address bar.  Then the included color_palettes/index.php file (which the server will automatically use when no filename is specified in the folder) will call the color_palettes/html-indexer.php file instead of generating a simple flat text-based index.  If you have sub-folders in your color_palettes/ folder, you can then copy the html-indexer.php file into those sub-folders, but then rename it index.php in those sub-folders so the server will automatically use it.  Don’t copy the included color_palettes/index.php file into sub-folders; it is not needed.

            Other folders and filenames may be changed or moved to suit your filesystem arrangement and organization.  You simply need to modify the <script> tags that actually load the files to match your new filepaths.  ¡The order the <script> files load is important!  You can defer them for faster page rendering.  As of 2022, the hard-coded <script> tag that defines the SoftMoon.WebWare & SoftMoon.loaded_palettes namespace properties should always go before any other MasterColorPicker files or Palette files.

            Developers should note that the files in the folder +++JS/ modify standard JavaScript Objects and/or their prototypes.  That is why they have been given thier own folder — to make it easier to keep track of in case of conflicts.

            Structuring your own HTML and CSS

            The first releases of MasterColorPicker focused on separating the JavaScript from the HTML and CSS as much as possible.  As the project evolved and bells and whistles were added, these three aspects of the project became more and more intertwined.  Modifying any aspect of the project will require careful testing.  In particular, the MyPalette interface is pretty tight.  The end of the MasterColorPicker.js file in particular relies on the standard HTML & CSS files.  Below you will find info on modifying older aspects of the project:

            The visual presentation of the individual color-pickers is up to you.  There are a few comments within the supplied HTML/PHP files which will not be repeated here; you should read them.  One general consideration concerns the <canvas> tag widths & heights;  you may modify them, keeping in mind that the color-pickers build their palettes based on the given width of the <canvas>, so it is best to keep the width/height of the canvases equal (excepting some of the canvases in the Simple² & YinYang NíHóng pickers).  The important requirements to follow are listed below for each of the color-pickers in the MasterColorPicker project:

            When the user clicks on a registered target element or it otherwise receives “focus,” the MasterColorPicker is activated.  When activated, the MasterColorPicker “main panel” and “options panel” (see the HTML), as well as the currently selected color-picker, all receive the classname “activePicker”.  There are other classnames added to various HTML elements in the MasterColorPicker under other various conditions.  For more detailed info on what classnames are applied and when, please see the comments in the JS_toolbox/SoftMoon-WebWare/Picker.js file.  To modify these used classnames, modify the values of the JavaScript properties of MasterColorPicker.classnames.  By understanding when and why these classnames are applied, you can create your own CSS file to control the dynamic display of the MasterColorPicker.

            Adding & removing color-pickers

            You may add your own color-pickers to, or remove individual color-pickers from the MasterColorPicker framework.  To remove one or more of the included color-pickers, simply remove its HTML and JavaScript from the given files.  The sections are clearly deliminated with comments.  The x_ColorPicker JavaScript Class is universal to all color-pickers in the MasterColorPicker framework, and should remain.  Don’t forget to lighten the weight of the CSS file, but that is not a requirement. 

            Adding your own (or someone else’s) color-picker is easy.  Its HTML should be included within the MasterColorPicker_mainPanel (see the supplied files), and its id should match the choice offered in the palette_select.  You should of course add this choice to the palette_select.  The palette_select choice may have spaces to match the “display name” of your added color-picker, and these will be removed when matching an id;  for example a choice of “YinYang NíHóng” corresponds to id “YinYangNíHóng”. 

            To interface another color-picker with the MasterColorPicker framework is easy, but as powerful things go, this process has details that must be understood to fully utilize.  Most simply, when a color is selected, using JavaScript, simply call MasterColorPicker.pick(……colorChoiceText……);  however this bypasses the central x_ColorPicker framework which can convert the choice to the user’s color-space preferences, and set the color of “color swatches”. 

            Using the x_ColorPicker framework is a bit different, as it is “event” oriented.  Please read the comments in the MasterColorPicker.js file regarding the x_ColorPicker framework, but here are some basic additional notes.  The x_ColorPicker framework offers a handleMouse method for onmouseover, onmousemove, and onmouseout events, and a handleClick method for onclick events.  They require two arguments passed in, yet browsers only pass in the first by default: the event object.  So you must either use your own event handler which calls these x_ColorPicker methods, or, more conveniently, use the UniDOM framework that is included with this package to add these methods as event handlers.  Take a close look (in the MasterColorPicker.js file at the end of each color-picker’s section) at how the supplied color-pickers add their event handlers using the UniDOM framework, and how the args object is passed on to the x_ColorPicker methods by adding it as a final argument passed to UniDOM.addEventHandler(………)

            Building your own color-pickers

            SoftMoon-WebWare’s Picker Class framework on which the MasterColorPicker is based is a powerful tool that creates an <input /> “type = picker”.  Your color-picker can be as complex as you need it to be, with multiple “interface panels,” interactive inputs that modify the picker and/or its choices, etc.  Please carefully read the JS_toolbox/SoftMoon-WebWare/Picker.js file and its comments about “registering” these interface panels and interface elements.  Registering them adds the necessary event handlers for them to work correctly with the MasterColorPicker framework.  Panels are registered using MasterColorPicker.registerInterfacePanel(……element……)  All HTML elements that require keyboard “focus” (such as <input type='text|file|number|etc.' /> <select> <textarea>) that are part of your picker but are not on a registered “interface panel” must be registered using MasterColorPicker.registerInterfaceElement(……element……)
