Abstract

Color management and color-managed workflow concepts are applied to lighting apparatus configured to generate multi-colored light, including lighting apparatus based on LED sources. In particular, color management principles are employed to facilitate the generation of variable color light from a given lighting apparatus based on any of a number of possible input specifications for a desired color. A transformation between an arbitrary input specification for a desired color and a lighting command (182) processed by the lighting apparatus is accomplished via the use of a source color management profile ( 180) for the input specification of the desired color, a target color management profile (172) for the lighting apparatus, and a common working color space. Colors defined in the common working color space may be reproduced or approximated by one or more lighting apparatus.
