摘　　要：目的:通过检测正常人群舌色与唇色的可见反射光谱色度学数据,统计正常人群舌色与唇色的色度学参数分布特性。方法:于广东省高等院校学生中筛选516例在读学生作为研究对象,应用可见反射光谱法采集舌色与唇色数据,进行CIEXYZ的颜色匹配三刺激值的计算,获得CIE1964色品坐标、明度、主波长、色纯度色度学参数。结果:应用可见反射光谱数据反演于CIE1964色度图,正常舌色的色品坐标x10为0.3413±0.0085,y10为0.3326±0.0051;正常唇色的色品坐标x10为0.3577±0.0092,y10为0.3383±0.0057;正常舌色与唇色的明度Y值分别为17.96±3.78和19.78±3.72;正常舌色与唇色的主波长值分别为(626.3±51.6)和(600.4±18.2)nm;正常舌色与唇色的兴奋纯度值分别为0.083±0.031和0.144±0.036。结论:应用可见反射光谱法对色诊资料采集可提供一种标准的测色方法,对正常舌色与唇色的色坐标、主波长与色纯度数据的检测与归纳总结,可以为病理的舌色与唇色的病证诊断提供基本参照。Objective： Using the data from normal tongue and lip colors of normal people which were collected by the visible reflection spectrum, we analyzed the colorimetric parameters of tongue and lip colors.Methods： In this study, 516 healthy students aging from 19 to 26 from the colleges and universities of Guangdong Province of China were taken as research subjects. After collecting the data of tongue and lip colors of the 516 subjects using visible reflectance spectroscopy, CIE XYZ tristimulus values as defined by the International Commission on Illumination in 1964 were calculated, and the colorimetric parameters of the normal tongue and lip colors were obtained, such as the CIE 1964 chromaticity coordinate, brightness, dominant wavelength and excitation purity.Results： The results of CIE 1964 chromaticity diagram calculated on the visible reflection spectrum showed that the normal tongue color chromaticity coordinate x10 was 0.341 3±0.008 5 and y10 was 0.332 6±0.005 1, and the normal lip color chromaticity coordinate x10 was 0.357 7±0.009 2 and y10 was 0.338 3±0.005 7; the brightness Y values of the normal tongue color and lip colors were 17.96±3.78 and 19.78±3.72, the dominant wavelength values of the normal tongue color and lip color were （626.3±51.6） nm and （600.4±18.2） nm, and the excitation purity values of the normal tongue color and lip color were 0.083±0.031 and 0.144±0.036, respectively.Conclusion： Application of the visible reflection spectrum is a standard way to collect colorimetric data for inspection of the complexion. The investigation of chromaticity coordinates, brightness, dominant wavelength and excitation purity of the normal tongue and lip colors may offer the basic reference for diagnosing morbid complexion on the tongue and lip colors in traditional Chinese medicine.
