Why doesn't peolp have the same colored eyes?

People have different colored eyes primarily due to genetic variations that influence the amount and type of pigments present in the iris. The main pigment responsible for eye color is melanin; higher levels result in darker eyes, while lower levels lead to lighter colors. Additionally, multiple genes are involved in determining eye color, leading to a wide range of hues and combinations. Environmental factors and evolutionary adaptations also play a role in the diversity of eye colors among populations.
