ABSTRACT:
A gamut mapping algorithm especially adapted for printing business and presentation graphics with highly chromatic colors. To perform gamut mapping, gamut triangles corresponding to an input gamut and output gamut are defined and used to scale the lightness and chroma of input colors. The rescaled input colors are then mapped to the output triangle along lines of constant chroma. The chroma of the remapped colors is enhanced by moving the remapped colors toward the apex of the output gamut triangle along a line passing through the remapped color and the apex of the output gamut triangle.
