Part II - Eye Coloration Puzzled, Alexia and Evan used the internet to research what gives the eye its color. "Eye color" refers to the color of the iris of the eye. Melanin is a dark pigment produced by cells in the iris that gives the eye its color. What determines the color of the eye is a combination of the amount, location, and qualities (e.g., different types) of the melanin present in the iris (Sturm & Larsson, 2009). The iris has a front layer and a back layer. The space in between them, called the stroma, is filled with various proteins, including white collagen fibers. For almost all eye colors, there is a lot of melanin on the back layer of the iris (Sturm & Larsson, 2009). Where people differ is in the melanin in the front layer of the iris. A lot of melanin in the front of the iris makes the eye look brown because, as light hits the front of the iris, the pigments absorb the light. Blue irises have less melanin in the front layer, so light can go through it. As light…
