ABSTRACT:
A method for defining a three dimensional neighborhood in a CMY color space. A CMY color space is provided having a gray line therein. The neighborhood is defined by defining boundaries thereof based on at least one correction H, S, L range with respect to the gray line. Changes within the neighborhood may be assigned weighting based on HSL positions of color points therein. With the invention, the hue, saturation, and luminance neighborhoods of a selected CMY color are determined directly from the original CMY image and CMY colors with respect to the gray line.
