Martin–Schultz scale
Encyclopedia
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 Martin and Schultz in the first half of the 20th century. The scale consists of 16 colors (from light blue to dark brown-black) that correspond to the different eye colors observed in nature due to the amount of melanin in the iris :

Eye color
Eye color is a polygenic phenotypic character and is determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris....
