Eye color is determined by 2 main factors pigments of eye’s and the frequency-dependence of the scattering of light. The appearance of blue, green, as well as hazel eyes is due to the Rayleigh scattering of light in the, it is similar to that which accounts for the blueness of the sky. In humans, the pigmentation of the iris varies from light brown to black, which depends on the concentration of the iris pigment called melanin.

In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium, the melanin content within the iris stroma , and the cellular density of the stroma. The appearance of blue, green, as well as hazel eyes is due to the scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky. Neither blue nor green pigments are ever present in the human iris or ocular fluid. Eye color is thus an instance of structural color and varies depending on the lighting conditions, especially for lighter-colored eyes.
