Blue, brown, hazel, green and all of the shades in between—there is one in the list that a small two percent of the population hold. Can you guess what the rarest eye color in the world is?
Rather, blue eyes result from structural color in combination with certain concentrations of non-blue pigments. The iris pigment epithelium is brownish black due to the presence of melanin. [54] Unlike brown eyes, blue eyes have low concentrations of melanin in the stroma of the iris, which lies in front of the dark epithelium.
Blue eyes actually contain no blue pigment. The colour is caused by an effect called Tyndall scattering. Blue eyes do not actually contain any blue pigment. Eye colour is determined by two factors: the pigmentation of the eye's iris [48] [49] and the scattering of light by the turbid medium in the stroma of the iris. [50]
In sectoral heterochromia, areas of the same iris contain two different colors, the contrasting colors being demarcated in a radial, or sectoral, manner. Sectoral heterochromia may affect one or both eyes. [31] It is unknown how rare sectoral heterochromia is in humans, but it is considered to be less common than complete heterochromia.
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 stroma, which is a thin layer of tissue in front of ...

The inheritance pattern followed by blue eyes was previously assumed to be a mendelian recessive trait, however, eye color inheritance is now recognized as a polygenic trait, meaning that it is controlled by the interactions of several genes.
