摘　　要： 翡翠颜色是翡翠质量和价值评估的重要环节之一。近年来有许多的学者针对翡翠颜色评价进行了各种研究,并且在学术方面取得了一定的成果,然而这些成果在市场上并没有得到广泛的运用与推广。笔者希望通过此次的研究找到一种简单快捷的翡翠颜色分级方法。本研究拟运用色度学HSL颜色空间模型对绿色翡翠的图像颜色进行色调、饱和度、明度的描述,并基于理论基础之上进行实践证明,即通过一系列针对绿色翡翠颜色数据的分析归类,最终得到各种绿色翡翠各自的HSL数值范围及阈值,并进行计算机编程。然后将通过计算机程序分级的绿色翡翠再运用肉眼感官和Gemdialogue色卡进行分级验证。最后证明基于HSL颜色空间模型对绿色翡翠颜色计算机分级技术的研究是具有可行性的。 The color of jade is one of the important linkages for evaluation of quality and value of jade. In recent years,many scholars have carried out various kinds of researches on the evaluation of jade color and have made certain achievements in respect of academic aspect. However,it is not difficult to find out that although the experts and scholars have made certain academic achievements on the evaluation of jade color,such achievements have obviously not been applied or promoted in the market. We hope that through this study to find a simple and quick method of grading the jade color. Through this research the hue,saturation and valueuses of green jade can be described by HSL color model,and the practice based on the theoretical basis,through the analysis of green jade color for a series of data classification and programming,and confirmed by visual sensory and Gemdialogue color grading test for green jade sample.Finally,proved that the computer programs about green jade＇s color classification is feasible.
