This is what causes hazel eyes and their many hues. Hazel eyes tend to change colors due to Rayleigh scattering—the same factor that makes the sky appear blue. This optical effect occurs in the ...
Hazel eye Hazel eye. Hazel eyes are due to a combination of Rayleigh scattering and a moderate amount of melanin in the iris' anterior border layer. [4] [35] Hazel eyes often appear to shift in color from a brown to a green. Although hazel mostly consists of brown and green, the dominant color in the eye can either be brown/gold or green.
Out of the conventional eye colors we'd think of—brown, blue, hazel and green—green is the rarest of the four. Only about two percent of the world's population has naturally green eyes.

Eye color, specifically the color of the irises, is determined primarily by the concentration and distribution of melanin. Although the processes determining eye color are not fully understood, it is known that inherited eye color is determined by multiple genes. Environmental or acquired factors can alter these inherited traits. [7]

For example, having eye color is a character of an organism, while blue, brown and hazel versions of eye color are traits. The term trait is generally used in genetics , often to describe phenotypic expression of different combinations of alleles in different individual organisms within a single population , such as the famous purple vs. white ...
Example of heterochromia – one eye of the subject is brown, the other hazel. Heterochromia (also known as a heterochromia iridis or heterochromia iridum) is an ocular condition in which one iris is a different color from the other iris (complete heterochromia), or where the part of one iris is a different color from the remainder (partial ...
