US Patent 7379208 Hybrid gamut mapping

In converting a color in a source gamut to a color in a destination gamut, selection of a conversion technique is determined for the source color based on the hue aspect of the source color, a maximum chroma of the destination gamut associated with the source color's hue aspect, and the lightness value of the source color relative to a lightness value associated with the maximum chroma. In converting a set of colors such as in a digital color image, selection of a conversion technique is performed for each color in the color image, independent of the color aspects of, and/or the conversion technique selected for, neighboring colors.
