Abstract

The spectral power distributions of white light-emitting diodes can be adjusted according to various demands. Thus, it is meaningful to explore the influencing law of monochromatic lights mainly in constructing white light-emitting diodes. Four kinds of typical red, yellow, green, and blue monochromatic lights were used to illuminate typical inorganic pigments. CIE XYZ coordinates were examined periodically, and then the color parameters—dominant wavelength, luminance, and excited purity—of the pigments were calculated through the data. The changing laws of the colors of the five pigments under different monochromatic lights were obtained. The relative influence values of the four monochromatic lights were also acquired through calculating and comparing the changing degree of the color parameters. The achievements can provide a data basis and reference for research on traditional Chinese paintings pertaining to color damage and the rendering effect of illumination.
