| Title: |
Color Management Methods and Apparatus for Lighting Devices |
| 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. In one example, a
transformation between an arbitrary input specification for a desired
color and a lighting command processed by the lighting apparatus is
accomplished via the use of a source color management profile for the
input specification of the desired color, a target color management
profile for the lighting apparatus, and a common working color space.
Colors defined in the common working color space may be reproduced or
approximated (e.g., according to one or more rendering intents) by one or
more lighting apparatus.
