| 摘 要： | 采用国际照明委员会CIE LAB色度坐标,定量描述了翡翠的绿色,分析了颜色的分布情况,总结其分布规律,建立起翡翠绿色L*、a*、b*、C*、hab的分布关系。当明度较小时,色调角几乎不变,彩度和明度呈现近似的线性相关;当明度变大时,色调角的变化幅度稍大,彩度值在明度中等偏低时变为最大。这些信息将在很大程度上对翡翠绿色分级的细化起到积极作用,可以用来指导翡翠色卡的制备。

| Abstract: | The green color of jadeite jade was measured and placed in the CIE LAB even color space. The distribution of color was analyzed in order to establish a relation of L*, a*, b*, C*, hab for the green color of jadeite jade. When L* is low, hab keeps relatively unchanging and C* and L* are linearly interrelated. When L* increases, the scope of hab increases a little and C* reaches its peak when L* is approximately 40. This information will have a positive effect on grading jadeite jade to a great extent in that it simplifies and guides the manufacture of jadeite jade color chips. |
