title: [Reproduction features of reflectance spectrum of natural plant flower color].
abstract: Based on the sRGB color space as an important color space of computer display, the authors explored color reproduction features in sRGB. In the terms of "color clipping" of color space transformation from CIE1931XYZ to sRGB, the color reproduction errors in sRGB of 218 reflectance spectra of natural plant flower color were examined. Considering the importance of D65 illumination, the reproduction features of natural color under D65 were emphasized. It was concluded as follows. Firstly, "color clipping" is the key cause of color transformation error of the natural plant color when it is transformed from CIE1931XYZ to sRGB color space. Secondly, under D65 eight orange and yellow reflectance spectra in 218 natural color show clipping in sRGB color space, accounting for 3.7% of all samples. Finally, the color reproduction of natural plant flower color in sRGB under D65 is the best, while the A illumination is the worst.
