Patent Number: 8665296 
Title: Color Generation Change Using Multiple Illuminant Types 
Abstract:

A system for generating a colored light comprises a set of illuminant types and a processor. The set of illuminant types is associated with a chromaticity gamut, and the set of illuminant types comprises at least five illuminant types that are each associated with an illuminant type hue angle. The processor is configured to determine, based at least in part on a mapping, a sequence of one or more output level sets that are associated with changing a first generated colored light associated with a first color coordinate to a second generated colored light associated with a second color coordinate. The mapping comprises associating each color coordinate with an output level set that uses a set of hue-adjacent illuminant types. Hue-adjacent illuminant types comprise a group of illuminant types that are determined to be adjacent in a circular ordered list of illuminant types which is circularly ordered according to the illuminant type hue angle.
