Abstract
A method and a system for a fast and reliable color reduction from multiple bit color representations to 4 bit color representations. The method for color reduction in a computer system having a three color model for color representation of a pixel, each color being represented by a multiple bit pattern, reduces the color to a four bit value by analysing the first bit of each of said three multiple bit patterns to determine tone; assigning a value to the first bit of said four bit value, based on said determined tone; and assigning the remaining three bits of said four bit value by utilising one pre-determined bit from each of said three multiple bit patterns.
