中文摘要：

目的：探讨典型舌色与复杂舌色的颜色特征和颜色空间分布特征。方法：从445例淡红舌中，选取典型淡红舌23例、偏紫舌36例、偏暗舌12例，从236例红舌中，选取典型红舌13例、偏紫舌20例、偏暗舌21例。采用Matlab软件，在CIELAB和LCH颜色空间中对各类舌色的数据及分布特征进行探讨。结果：（1）淡红舌的明度最高，色相偏于红黄。（2）红舌的明度减低，彩度加大。（3）典型淡红舌、典型红舌的特征为明度和彩度均加大。（4）偏暗舌以明度的减低为著。（5）偏紫舌的特征为色相偏红紫色。（6）偏紫舌与偏暗舌在CIELAB和LCH颜色空间中所处的空间位置不同。结论：典型舌色与复杂舌色的颜色不同。在颜色空间的位置不同。

英文摘要：

Objective： To investigate the color values characteristic and the space distribution characteristic of the typical and complicated tongue color. Methods From the 445 cases of the light red tongue diagnosed by the doctor, 23 cases of the typical light red tongue, 36 cases of the amphi-purple tongue and 12 cases of the amphi-dark tongue had been chosen. From the 236 cases of the red tongue, 13 cases of the typical red tongue, 20 cases of the amphi-purple tongue and 21 cases of the amphi-dark tongue had been chosen. Using the Maflab software, the different tongue color values datum and the space distribution characteristic had been studied in the CIELAB and LCH color space. Results：（ 1 ） The lightness of the light red tongue color was highest and the hue of those was prefer to the red-yellow color. （2） The red tongue color had the lower lightness and the higher chroma compared with the light red tongue color. （ 3 ） The lightness and chroma of typical light red tongue color and typical red tongue color were higher. （ 5 ） The amphi-purple tongue color appeared the hue change. （6） The amphi-purple and the amphi-dark tongue color occupied the different space location in the CIELAB and LCH color space. Conclusions：The typical and complicated tongue color had the obvious difference of the LabCHcolor parameter, and occupied the different space location in the color space.
