ABSTRACT:
Meeting a target color point using more than 3 primary light sources is achieved by calculating permutations of light sources, calculating for each of the permutations the contributions of the light sources to meet the color point, adding up the contributions of the light sources separately into an overall contribution, and operating the light sources according to their overall contributions.
