Hex and RGB values are calculated from the native format, and others are calculated from the RGB values.
RGB values may be rounded off to integers in the process yielding differences that are especially noticeable in Hue values.
(More minor round off errors will always be possible due to floating-point mathematics used by computers.)
Note RGB values will always be shown as integers, and are always used internally by the computer’s hardware
as integers, so by not keeping precision, resulting conversions from the RGB values reflect
the “used RGB” values.
Valid values for colors include:
When used as a grid-fill, the 1D fills are aligned vertically (y-value of the 2D grid),
with the span between them being horizontal (the x-value of the 2D grid).
When used as a radial-fill, the 1D fills are aligned along a polar ray (radius-value of the 2D grid),
with the span between them based on a pie-wedge percentage (angle-value of the 2D grid).
Fills may be applied to a Rainbow Shape as a Radial or Grid fill, regardless of the Model used to build the fill.
The @ symbol allows the span between 1D-fills to be controlled by
the “width” values of those fills.
Use 1D gradients to build 2D gradients. Apply gradients as fill for Sculpted Rainbow shapes below.
¡Warning! This is a very slow process!
