| Title: |
Color Generation 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 an illuminant type hue
angle. The processor is configured to determine, based at least in part
on a mapping, an output level set for a received 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 that is
circularly ordered according to the illuminant type hue angle.
