Claim of US Patent No. 9,565,734

1. A computer-implemented method of generating a color mixing model, the method comprising:
dividing multiple color channels into one or more non-floating channels and one or more floating channels;
inversely-solving one or more lumens values of the floating channels at an operating point of the non-floating channels corresponding
to a source state record based on measured spectral characteristics of the non-floating channels;

determining whether a gamut area, defined by the inversely-solved lumens values of the floating channels and the operating
point of the non-floating channels, includes a target color point; and

responsive to determining that the gamut area includes the target color point, defining an entry in the color mixing model
mapped to the target color point based on the inversely-solved lumens values; and

wherein the entry in the color mixing model instructs a color-tunable lamp to produce the target color point by driving the
multiple color channels according to the inversely-solved lumens values and the operating point of the non-floating channels.
