1. A color mixing method for variable color lighting, wherein first to third light sources of mutually different emission colors are prepared, another light source of another emission color the chromaticity coordinates of which are disposed within a figure drawn on a chromaticity diagram by connecting respective chromaticity coordinates of emission colors of a plurality of light sources including said first to third light sources is prepared, a temporary light source is imaginarily set by mixing said emission color of one of said plurality of light sources including the first to third light sources with said another emission color of said another light source, a mixing ratio of the emission colors of at least two remaining light sources in said plurality of light sources including the first to third light sources and of said temporary light source is calculated, and a further mixing ratio of required emission colors of the respective light sources for obtaining a mixed color light which draws a desired locus on said chromaticity diagram is obtained on the basis of said mixing ratio calculated.
