The color of the iris usually varies from light brown, dark blue to black. Eye color that varies is usually determined by the amount of melanin, which is a brown pigment found in the eye, called the iris. If the eyes are blue, this is caused by at least the amount of melanin, but if the eye is brown, it means the amount of melanin contained a lot.
People with hair color and skin darker have more melanin, so their eyes are brown, while the color of the hair and skin paler have less melanin amount so that their eyes are usually lighter-coloured.
