两种类型的便携式反射仪器，三刺激色度计（色度计CR-200）和窄带色度计（Dermaspectrometer），最近已成为可用于皮肤颜色的量化。为了了解不同颜色系统（CIE L*a*B* 系统和红斑黑色素（E/M）指数）之间的差异和关系，测量了10名健康白人男性受试者23个不同解剖部位的肤色变化。在a* 值或E指数的增加中，面部、手掌和脚掌的皮肤颜色的微红色很容易被它们中的任一个检测到，并且在两个值之间注意到强的线性相关（r = 0.92，p < 0.001）。在高L* 值和低M指数时，躯干的外观颜色较好，但两者之间的相关性不显著（r =-0.56，p < 0.001）。虽然躯干的平均B* 值最高，但臂的非光照侧显著低于光照侧，B* 值与M指数之间的相关性较弱。
Two types of portable reflectance instruments, tristimulus colorimeters (Chroma Meter CR-200) and narrow-band spectrophotometers (Dermaspectrometer), have recently become available for the quantification of skin color. In order to know the difference and the relationship between the different color systems, the CIE L*a*b* system and the erythema melanin (E/M) indices, respectively, adopted by the two, the variations in skin color were measured at 23 different anatomical sites of 10 healthy Caucasian male subjects. The reddish tint of the skin color of the face, palm and sole was readily detected by either of them in the increase in the a* value or in the E index, and a strong linear correlation (r = 0.92, p < 0.001) was noted between the two values. The fair color appearance of the trunk was detected in the high L* value and in the low M index, but the correlation between the two was much less significant (r = -0.56, p < 0.001). Although the mean b* values were highest in the trunk, they are significantly lower on the non-light-exposed side than those on the light-exposed side of the arm. The correlation between the b* value and the M index was weak.
