The Martin scale is an older version of color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual; it was created by the anthropologist Martin in the first half of the 20th century. Later he improved this scale with cooperation of dr. Schulz – the Martin-Schultz scale.

Original scale
The original Martin scale eye color chart is shown below. 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. The numbering is reversed in order to match the Martin–Schultz scale, which is still used in biological anthropology.
Light and light-mixed eyes (16-9)
Mixed eyes (8-7)
Dark-mixed eyes (6-5)
Dark eyes (4-1)
