In a display system, a color gamut of the displayed images is extended by adding one or more primary colors lying outside a tristimulus color space triangle to a Red, Green, Blue (RGB) system, modulating light emitted by both light sources lying inside the tristimulus color space triangle and light sources lying outside the tristimulus color space triangle, and adding a non-tristimulus vertex to construct an extended-gamut polygon. The display system adds one or more primary colors to the RGB system, which lie outside the tristimulus color space triangle but within a CIE (International Commission on Illumination) color space.

The invention claimed is: 1. A method for extending a color gamut comprising:generating red, green and blue light using respective first light sources, said red, green and blue light having a color space represented by a tristimulus color space triangle;adding light of an additional color located outside said tristimulus color space triangle to said red, green and blue light to provide light having a color space represented by an extended-gamut polygon having a non-tristimulus vertex, said adding comprising generating said light of said additional color using a second light source; andmodulating said light emitted by both said first light sources lying inside said tristimulus color space triangle and said light source lying outside said tristimulus color space triangle;wherein said generating said light of said additional color comprises combining light from light sources generating light of colors that chromatically sum to said additional color based on their weighted intensities.
