摘要─皮肤中的蓝色来自胶原蛋白和黑色素之间的特定光学关系，这导致从真皮反射的光中的“减色混合”。在这种类型的颜色产生中不重要的是光的散射，黑色素的红棕色透射颜色，以及一般表皮的光学特性。在灵长类动物中，血色素在改变蓝色方面具有辅助作用。这表明，发绀可能并不总是意味着存在减少或异常血红蛋白。皮肤黑素细胞系统的进化意义与色觉、新陈代谢、保护和社会性功能有关。
SUMMARY.— Blue colours in the skin arise from a particular optical relationship between collagen and melanin which leads to a “subtractive colour mixing” in the light reflected from the dermis. Unimportant in this type of colour production are scattering of light, the red‐brown transmission colours of melanin, and the optics of the epidermis in general. In primates the blood pigments have an adjuvant effect in varying the blue colour. It is suggested that cyanosis may not always imply the presence of reduced or abnormal haemoglobin. The evolutionary significance of the dermal melanocyte system is briefly mentioned in relation to colour vision, and sundry metabolic, protective and socio‐sexual functions.
