Martin scale match the Martin–Schultz scale, which is still used in biological anthropology. Older versions of the Martin scale eye color chart have the following color divisions: Martin scale 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. The original Martin scale, summarized below, consists of 16 colors (from light blue to dark brown-black) that
Linguistic relativity and the color naming debate the study of color naming phenomena. He states that "the physics of color, the psychophysics of color discrimination, and the psychology of color naming are not isomorphic". The color spectrum clearly exists at a physical level of wavelengths (inter al.), humans cross-linguistically tend to react most saliently to the primary color terms (a primary motive of Bornstein's work and vision science generally) as well as select similar exemplars of these primary color terms, and lastly comes the process of linguistic color naming, which adheres both to universal patterns but demonstrates individual uniqueness. While one may have origins in its predecessor,
