Martin-Schultz scale. The Martin–Schultz scale is a standard color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual; it was created by the anthropologists Rudolf Martin and Bruno K Schultz in the first half of the 20th century.

The total number of genes that contribute to eye color is unknown, but there are a few likely candidates.
