Abstract: A color conversion method maps input colors to output colors by first scaling the color coordinate system to reduce the difference between the gamut of reproducible input colors and the gamut of reproducible output colors. After scaling, input colors are mapped onto a polyhedron approximating the gamut of reproducible output colors. The polyhedron has vertices at the output white and black colors, and at least three of the most vivid reproducible output colors. In the mapping process, these most vivid colors are left fixed, and the input white and black colors are mapped to the output white and black colors.
