Factors Affecting Eye Color
Eye color is primarily determined by the amount and distribution of melanin in the iris. The more melanin present, the darker the eye color will be. However, eye color can also be influenced by other factors such as genetics, age, and even mood. For example, some people’s eye color may appear to change based on the lighting or the colors they are wearing.
