    • The present invention relates to a method of generating light with a predetermined chromaticity value of a color gamut by color mixing of the light emitted by a plurality of light sources, each of which emits light with a primary color, the light sources being capable of emitting light with at least three primary colors, wherein at least a first and a second light source are used to emit light of at least one primary color. The object to provide a simple method of generating light with a predetermined and constant chromaticity value of a color gamut by color mixing of the light emitted by a plurality of light sources, which can even be advantageously used in display applications sequentially displaying primary colors, is achieved in that said first and said second light source emit light with different peak and/or dominant wavelengths, the chromaticity of the primary color generated by color mixing of the light emitted from said first and said second light source being adjusted to a predetermined and constant chromaticity value by controlling the ratio of intensities of said first and said second light source, and said chromaticity value of said primary-color light generated by color mixing is used to generate light by color mixing with the light of other primary color light sources.
