AlthoughL*2000 contributes most toE*2000 (r=0.854), taking consideration of variation range of purple is wide in color science, it is extremely not rigorous if we ignore the influence of H*2000 orC*2000.L*2000 less thanH*2000 andC*2000 for all the lavender of jadeite parameters affecting the appearance.
In addition, hue and chroma is the basic important parameters in color science.
Upon the comparative of material object and the photos by numerous people contrast many times, we can find that y1 tends to be partial to blue and y2 tends partial purple.
The variation range of purple is wide in color science because it is the most broad one from partial red purple till partial blue purple.

Composite material was selected for the shells in this analysis.
It is assumed that R/t = 40 and L2/Rt = 800, all plies are of equal thickness and the total thickness of the shell is t = 3.0 mm and the material properties (Vetrotex E glass fibers, My 750 epoxy resin), adopted as in Messager (2002), are: E11 = 45.6 GPa, E22 = 16.2 GPa, G12 = G13 = 5.83 GPa, G23 = 5.78 GPa, and = 0.278.
