Abstract
A method of color processing determines whether a pixel color is within at least one range of predetermined colors corresponding to a viewer expected color. If so, the method altering the pixel color to better approximate the viewer expected color. For detection of skin tones determining whether the pixel color is within a range of predetermined colors includes discounting an illuminant of the pixel color. The viewer expected colors are preferably skin tone, grass green and sky blue. The saturation level of grass green and sky blue are enhanced and that of skin tones are suppressed. The saturation s is limited based upon lightness J and hue h to convert to an allowable RGB color format range.
