Abstract: Methods and systems for measuring with a Color Measurement System of predetermined specification and evaluating the color of skin, teeth, hair and material substances with a Color Index. The principles of this invention also relate to techniques for using such a Color Measurement System with the Color Index in medical applications such as the detection of chromogenic disease including bilirubin infant jaundice, cosmetics applications and in the evaluation of the color of hair or teeth, and other applications. The Color Index is measured and calculated from the reflectance spectrum of any skin (or teeth, hair or material substance) by a two step process. The first step is the weighting of the visible spectra with a unique set of weighting factors which calculate a sample's reflectance spectrum's contribution to the appearance of four color components independent of the illuminating condition. The second step places the sample's reflectance spectrum's contribution to the appearance of the four color components in opponency to each other and calculates the Color Index providing attributes representative of correlates of lightness-darkness (L, also referred to as lightness), redness-greenness (M) and yellowness-blueness (N).

Abstract translation: 使用预定规格的色彩测量系统进行测量的方法和系统，并用颜色索引评估皮肤，牙齿，头发和物质物质的颜色。 本发明的原理还涉及在医疗应用中使用具有颜色指数的这种颜色测量系统的技术，例如检测包括胆红素婴儿黄疸在内的显色疾病，化妆品应用和对头发或牙齿颜色的评估，以及 其他应用。 颜色指数通过两步法从任何皮肤（或牙齿，毛发或物质物质）的反射光谱测量和计算。 第一步是使用独特的一组加权因子对可见光谱进行加权，这些加权因子可以计算样本的反射光谱对独立于照明条件的四种颜色分量的出现的贡献。 第二步将样本的反射光谱对对方的四个颜色分量的出现作出贡献，并计算提供颜色指数的颜色指数，该属性表示亮度 - 黑暗（L，也称为亮度），发红度（红色） M）和淡黄色（N）。
