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 total number of genes that contribute to eye color is unknown, but there are a few likely candidates. A study in Rotterdam (2009) found that it was possible to predict eye color with more than 90% accuracy for brown and blue using just six SNPs. [16] [17] In humans, eye color is a highly sexually dimorphic trait. [18]
The Hunt and RLAB color appearance models use the Hunt–Pointer–Estevez transformation matrix (M HPE) for conversion from CIE XYZ to LMS. [4] [5] [6] This is the transformation matrix which was originally used in conjunction with the von Kries transform method, and is therefore also called von Kries transformation matrix (M vonKries).
An eye-color surgery called keratopigmentation is gaining attention online, but experts aren't convinced it's safe. A woman paid $12,000 for surgery to permanently turn her eyes from brown to blue.
Chromatic adaptation is the human visual system’s ability to adjust to changes in illumination in order to preserve the appearance of object colors. It is responsible for the stable appearance of object colors despite the wide variation of light which might be reflected from an object and observed by our eyes.
