Abstract
The study of skin color has recently undergone some developments. In 1949 the senior author published a chart of eight individual skin colors ranging from full black to white, which can be used in recording the skin color of persons of mixed descent (1). In making use of this chart, certain modifications have been found necessary, and a new genetic theory of skin color has been developed (2). As a different approach to the subject, spectrophotometer reflectance curves of various human skin colors have been published, including those of the original chart (3). In a further effort to analyze the nature of the differences between various skin colors, it was considered desirable to make a histologic study of the skin of different individuals from biopsy specimens.
