1. A method of compressing a color cell including a plurality of pixels, said method comprising: (a) determining a vector that represents a best-fit of color values of said pixels; (b) distributing at least four representative color values along said vector; (c) comparing color values of said pixels with said representative color values; (d) generating at least two bitmasks to represent said color cell, said bitmasks for storing data identifying one of said representative color values that is closest to a color value of a corresponding texel; and (e) appending said four representative color values to said bitmasks.
