1. A method, comprising:

  • receiving data encoded with a color point;

    deterministically calculating dimming values for each of four or more light sources without using a look-up table of the dimming values to generate a color point, wherein the combined output of the four or more light sources generates the color point;

    solving for a plurality of dimming values for each of a plurality of three-color combinations of the four or more light sources using the received data; and

    summing the plurality of dimming values for each of the plurality of three-color combinations using superposition, wherein the combined output of the four or more light sources generates the color point.
