The color of the iris, the part of the eye that surrounds the pupil, is determined by the pigmentation and density of melanin in the iris. Melanin is a pigment that gives color to various parts of our body, including our skin, hair, and eyes. The amount and distribution of melanin in the iris are determined by genetics and can vary widely among individuals. This variation leads to different eye colors, such as brown, blue, green, or gray. Factors like the amount and type of melanin present in the front layers of the iris, as well as the scattering of light inside the eye, also play a role in the perceived eye color.
