displayable=truefalse := false

If this keyword is given then each output color will be displayable, and when represented in the "RGB" color space all three component values of each output color will be between 0 and 1. The default value for this option is false.

markers=list or Array

The parameter thresholds corresponding to each of the specified input colors.

space=string

The color space in which to compute the intermediate colors; if unspecified, this is inferred from the colors spaces of the input when possible, defaulting to "RGB" otherwise.

The Blend command generates a blend of the specified colors.

The first parameter specifies the colors to blend. This may be a range color1..color2 or a list or palette of colors.

The second parameter value specifies a point at which to interpolate.

For example, Blend(red..blue,3/4) will produce a blend of 3/4 blue and 1/4 red.
