Abstract:
1. A system for generating a target chromaticity, comprising: at least four color sources, each of the color sources having a chromaticity determined by hue and saturation, each of the color sources having a range of available color source intensities, the at least four color sources including four or more vertex color sources forming vertices of a gamut area having a shape of a convex polygon, the at least four color sources including at least four sets of three color sources to define at least four partially-overlapping, two-dimensional, triangular sub-gamut areas in which each set of three color sources has a corresponding sub-gamut area, the chromaticity for each color source within each of the sets of three color sources forming a vertex of the corresponding sub-gamut area, the target chromaticity being contained within the gamut area and within at least two of the sub-gamut areas; and a controller configured to calculate a final solution to form the target chromaticity within the gamut area using the at least four color sources and control the intensities of the at least four color sources to produce the target chromaticity, wherein the controller is configured to:
