ColorTools

 Gradient
 generate a selection of intermediate colors

 Calling Sequence Gradient(color1..color2)

Parameters

 color1,color2 - colors in formats recognized by ColorTools

Options

 • number=nonnegint
 • the number of intermediate colors to compute (default is 10)
 • space=string
 • the color space in which to compute the intermediate colors by default this is inferred from the colors spaces of the input.
 • best
 • if this keyword is given, a heuristic is used to get a well spaced set of colors
 • displayable
 • if this keyword is given, the output colors will all be displayable

Description

 • The Gradient command computes a number of intermediate colors that transition between the two colors in the input range.
