Abstract: A first method for matching skin colours comprises measuring a spectral reflectance curve of an area of skin and determining a blend of pigments to match the skin's colour by combining spectral reflectance curves measured for pigments to produce a calculated spectral reflectance curve corresponding to that of the skin. The pigment blend is then used, for example, to pigment a medical prosthesis, so that it matches precisely its wearer's skin. This method avoids the problem of metamerism in which colours that match under a first illumination (such as incandescent light) no longer match under a second illumination (such as daylight). A second method uses a database of pigment blends generated by the first method. The colour of an area of skin is measured and a pigment blend is selected from the database that provides a closest match. Apparatus for carrying out such colour matching is also provided, together with palettes of suitable pigments for skin colour matching.
Abstract translation: 用于匹配皮肤颜色的第一种方法包括测量皮肤区域的光谱反射率曲线，并通过组合针对颜料测量的光谱反射率曲线来确定颜料的混合以匹配皮肤的颜色，以产生对应于皮肤的光谱反射率曲线 。 然后将颜料混合物用于例如染色医用假体，使其与其佩戴者的皮肤精确匹配。 该方法避免了在第二照明（例如白天）下在第一照明（例如白炽灯）下匹配的颜色不再匹配的同色异谱的问题。 第二种方法使用由第一种方法生成的颜料混合物的数据库。 测量皮肤区域的颜色，并从提供最接近匹配的数据库中选择颜料混合物。 还提供了用于进行这种颜色匹配的装置，以及用于皮肤颜色匹配的合适颜料的调色板。
