In humans, eye color is a highly sexually dimorphic trait. [18] Several studies have shown that men are more likely to have blue eyes than women, while women are more likely to have darker eye colors (green and brown eyes) than men. [18] [19] Sex is therefore a major factor in the expression of eye color genotypes. [18]
Grey eyes make up about 3 percent of the world's population—the second rarest eye color. There are also rare cases of violet and red-colored eyes. What Determines Eye Color?
With most eye colors, the amount of melanin is consistent across the entire iris—the more melanin, the darker the eye will appear. With hazel eyes, however, varying amounts of melanin exist in ...
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]
Amber eyes are a solid color with a strong yellowish/golden and russet/coppery tint, which may be due to the yellow pigment called lipochrome (also found in green eyes). [39] [40] Amber eyes should not be confused with hazel eyes. Although hazel eyes may contain specks of amber or gold, they usually tend to have many other colors, including ...

Magenta is variously defined as a purplish-red, reddish-purple, or a mauvish–crimson color. On color wheels of the RGB and CMY color models, it is located midway between red and blue, opposite green. Complements of magenta are evoked by light having a spectrum dominated by energy with a wavelength of roughly 500–530 nm.
Melanin is the protein that creates skin, eye and hair color. More melanin means darker eyes, hair or skin. The color of the melanin in the eyes is determined by three other genes, EYCL1, 2 and 3.
