Abstract:
An aspect of present principles is directed to methods and systems for gamut mapping source colors into target colors from a source color gamut towards a target color gamut. A difference may be determined source specific colors and corresponding target specific colors. A source hue of the source specific colors is adaptively changed towards a target hue of the corresponding target specific colors based on the difference to determine mapped specific colors. Color gamut mapping is performed for the source colors of the source color gamut towards the target color gamut based on the mapped specific colors. The specific colors are selected from primary colors, secondary colors, a group of primary colors and secondary colors. The difference is based on at least one selected from the group of hue, saturation and lightness of the source specific colors and the corresponding target specific colors.
