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 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 ^{[1] [2]}:

• 1-2 : blue iris (1a ,1b ,1c ,2a : light blue iris - 2b : darker blue iris)
• 3 : blue-gray iris
• 4 : gray iris
• 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
• 9-11 : light-brown iris
• 10 : hazel iris
• 12-13 : medium brown iris
• 14-15-16 : dark-brown and black iris
