Detailed explanation-1: -Eye color is directly related to the amount of melanin in the front layers of the iris. People with brown eyes have a large amount of melanin in the iris, while people with blue eyes have much less of this pigment. A particular region on chromosome 15 plays a major role in eye color.

Detailed explanation-2: -The amount of this pigment (called melanin) in the iris of your eye determines the color of your eyes. Eyes with very little melanin in the iris are blue. Eyes with a bit more melanin are green, hazel or light brown. And those with a high concentration of melanin are medium or dark brown.

Detailed explanation-3: -The cells in the iris that make pigment are called melanocytes, and they are also responsible for the color of our hair and our skin. Melanocytes can make two different types of pigment: eumelanin, which is brown-black, and pheomelanin, which is red. Dark eyes have the most pigment, particularly brown-black eumelanin.

Detailed explanation-4: -What are Nevi? Nevi (Brown spots in the eye) are created by pigment cells, otherwise known as melanocytes clumping together, similar to how freckles or moles grow on the skin. These pigment cells also produce melanin that colours the hair, skin, and eyes.

Detailed explanation-5: -Eye color depends on melanin. Melanin is a brown pigment in the eye’s iris, and the type, amount, and distribution of melanin in the iris determines its color.
