1. A method for generating a compressed representation of image pixel colors using stored color values in a lookup table (LUT) to form display pixel colors, comprising the steps of:

  • sampling said image pixel colors with equal probability to generate a first set of said stored color values;

    sampling said image pixel colors with equal probability to generate a sequence of actual image colors;

    determining a closest one of said stored color values to each of said actual image colors;

    forming an average color value from said closest one of said stored color values and said actual image color; and

    updating said closest one of said stored color values with said average color value.
