A color management system that transforms input image data from an input colorant space to an output colorant space using input and output device appearance transforms and a customizable gamut mapping algorithm. The gamut mapping algorithm is customizable based on the color management session in question, and in particular may be customizable based on the content of the image data, based on a comparison between input device appearance transforms and output device appearance transforms, or based on viewing conditions, output conditions or print media involved. According to the invention, the customizable gamut mapping algorithm is customized based on the current color management session, and the customized gamut mapping algorithm is composited with the input device appearance transform and/or the output device appearance transform thereby yielding one or more transformations that can be applied to the input image data more efficiently than if the transformations (including the gamut mapping algorithm) were applied individually.
