Gradient(color1..color2)
color1,color2
-
colors in formats recognized by ColorTools
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 using the Jab perceptual color space.
displayable
if this keyword is given, then each output color will be displayable
The Gradient command computes a number of intermediate colors that transition between the two colors in the input range.
