Patent ID: 8723450

Claim:
A method of controlling the output of a light fixture, the light fixture including four or more light sources, the method comprising: identifying a first output value for each of the four or more light sources based on a target color; driving the four or more light sources at the first output value for each of the four or more light sources to produce the output of the light fixture, the output of the light fixture substantially corresponding to the target color and having a first spectral content; receiving a modification signal associated with a modification to the first output value of at least one of the four or more light sources, the modification signal corresponding to a change in the first spectral content; identifying a second output value for each of the four or more light sources based on the modification signal; and driving the four or more light sources at the second output value for each of the four or more light sources to produce the output of the light fixture, the output of the light fixture substantially corresponding to the target color and having a second spectral content that is different from the first spectral content.
