Patent Number: 8633649 
Title: System and Method for Color Creation and Matching 
Abstract:

Systems and methods for controlling an output of a luminaire. The luminaire uses stored spectral information for light sources within the luminaire to determine a coordinate for each light source within a color space. A desired output color is also converted to a coordinate within the color space. The distance between the desired output color coordinate and each of the coordinates corresponding to the light sources is calculated to select initial control values for the light sources. The initial control values for each light source are individually modified by a step size value, the total output of the luminaire is calculated and converted to a coordinate within the color space, and the distance between the total luminaire output coordinate and the desired color coordinate is calculated. The control values for the light sources are iteratively modified until the luminaire output coordinate is within a threshold value of the desired color output.
