The Difference of Jadeite-Jade Lavender under Three Light Sources

Abstract:

Compare the different appearance of jadeite-jade with three standard light sources, daylight D65,incandescent light A and fluorescent light F2(CWF),whose colors are purple to bluish violet with low chroma and low lightness in. The analysis of color index in the CIE 1976L* a* b uniform color space shows that the hue of lavender is influence by the light of standard light sources, followed by chroma, simultaneously value is seldom influenced obviously. And the color saturation of purple jade samples with CWF is usually higher, showing more vivid purple. However, D65 is benefit to the lightness of the purple jade, in which the average of color differences is known as the largest while the variance is the smallest. As D65 can be used to distinguish the purple color of jade samples most greatly, it is intended to be the best light source for appreciation of jadeite-jade. In consideration of the better quality of the purple color displayed with the CWF, it can be used during business transaction process.
