Methods Retrospective analysis of 22 studies of tongue color classification data, the tongue color values were converted to L*、a*、b*、C*、H*, carried out the comparison among various types of tongue color chromaticity values, and observed the distribution of all kinds of the tongue color in CIELAB and CIELCH color space. K-means clustering method is used to achieve the clustering of tongue color chromaticity values, and a chromatic aberration analysis is launched. Results A total of 22 articles reported on 11 categories of tongue color, and it is more than the six categories reported by Chinese Medicine Diagnosis textbook. A value range of 11 types tongue color brightness is from 45 to 60, hue angle between the 8° - 27° and 320° - 355°, saturation between 17 and 36. Regular ch
