Claim of US Patent No. 10,172,210

18. A method of generating drive conditions for one or more light sources to maintain a desired color of a light emitted by the one or more light sources, as perceived by a human observer, over a change in a reference luminance, the method comprising:determining a corrected color that produces perception of the desired color, by a human observer, when a specific reference luminance is present;
determining drive conditions for the one or more light sources to produce the corrected color; and
determining the change in the reference luminance, wherein determining the change in the reference luminance comprises:
receiving, at a luminaire that includes the one or more light sources and an additional light source that supplies the reference luminance, a user input to change the reference luminance;
providing additional drive conditions, by the luminaire, to the additional light source to change the reference luminance;
and wherein determining the change in the reference luminance is based at least in part on a known response of the additional light source to the additional drive conditions.
