目的:遵循颜色科学的理论与技术,探讨中医舌色的分析方法。方法:根据中医舌色的视觉诊断过程,采用CIELAB均匀颜色空间作为舌色分析的平台,将所采集的舌色RGB数据转换到CIELAB空间,研究与视觉感受对应的舌色色域分布规律。结果:提出一种数值拟和的方法,对中医描述的舌色（红舌,淡红舌,淡白舌等）进行分类,并根据舌色的分布,提取各类舌色的典型特征色。结论:这种分类和特征色的提取方法能够表示中医舌色的实际视觉描述分类关系,具有一定的可行性。

This paper discusses tongue color analysis techniques used in Traditional Chinese Medicine,under the enlightening of modern color sciences and techniques.Based on the traditional process of tongue color diagnosing, we filled the collected RGB color data in CIELAB color space, using the latter as a platform. Then we measured the gamut of tongue display. We have created a numerical process for classifying tongue colors, based on the traditional process （for example: light white tongue, light red tongue, red tongue）, and screened out typical colors for each tongue pattern. We believe that the novel approach has produced a good result for both description and classification of tongue colors, that can be compared with the results of human visions. It can be applied in clinical diagnosis.
