1. A method for transforming input color values in an input color space to output color values in an output color space, comprising the steps of: a) forming a transform for only the input color values that are neutral; b) forming a transform for transforming a plurality of highly saturated input color values to specified desired output color values, said plurality of highly saturated input color values being less than all of the highly saturated input color values; c) forming a transform of the remaining colors using as boundary values the transform for input color values that are neutral, as formed in step a), and the transform for the highly saturated input color values, as formed in step b); and d) transforming input color values in the input color space to output color values in the output color space using the transforms formed in steps a), b), and c).
