Abstract
A color palette mapped to an image obtained by any known process is decomposed to separate contrast components from hue/saturation pairs, then only the hue/saturation pairs are remapped to a new set of hue/saturation parameters according to available mapping techniques, including remapping of ordered color sets, into a new ordered set wherein at least a portion of the contrast components are held at fixed values and not altered. By fixing the contrast components, color remapping is constrained to certain symmetric transformations in Munsell color space which preserves features of the source image in the resultant image.
