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 scale consists of 20 colors[1] (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:[2][3]
- 1-2 : blue iris (1a, 1b, 1c, 2a : light blue iris - 2b : darker blue iris)
- 3 : blue-gray iris
- 4 : gray iris (4a, 4b)
- 5 : blue-gray iris with yellow/brown spots
- 6 : gray-green iris with yellow/brown spots
- 7 : green iris
- 8 : green iris with yellow/brown spots
- 9-10-11 : light-brown and hazel iris
- 12-13 : medium brown iris
- 14-15-16 : dark-brown and black iris
