Abstract
Systems and methods for illumination and color management in a system having a plurality of color sources and a plurality of color sensors, wherein there are more color sources than color sensors are described herein. An embodiment of the method includes emitting a plurality of different colors of light from at least two of the color sources, wherein the plurality of colors consist of different intensities of light emitted by the plurality of color sources. Colors of light emitted by the at least two color sources are detected using at least one of the color sensors. The color rendering index for each of the plurality of colors emitted is determined. A color of light to be emitted by the light sources is selected. The intensities of light to be emitted by the color sources is selected, based at least in part on the color rendering index, to achieve the selected color of light.
