Abstract
The chlorophylls and cartotenoids are the main pigments in leaves of the higher plants, which giveing the color of leaves. Based on the CIE1931 chromaticity coordinates of the chlorophylls and cartotenoids obtained from their classical absorption spectrum and the law of additive color mixing, the theoretical color gamut of higher plant leaves is determined. The theoretical prediction agrees well with the experimental results.
