Color management using a discrete spectral gamut descriptor. A multi-spectral color image is converted to a spectrally-based ICS representation. In response to a determination that an ICS value is included in a discrete spectral gamut descriptor, the ICS value is converted into a destination-side color. Otherwise, the ICS color value is spectrally gamut mapped, and the gamut-mapped ICS value is converted into a destination-side color. The discrete spectral gamut descriptor includes a collection of discrete cells of a subdivided bounding box that includes a set of sample points in the ICS that span the spectral gamut of the destination device. Each cell has an attribute that represents an initial guess for a destination-side color for ICS values included in the cell, and the attribute is used to convert ICS values included in the cell into destination-side colors. |
