  • While melanin is what technically gives the eyes their color, it’s the eye colors of a baby’s parents — and to a certain extent, of your great-great-great uncle and your great grandma and all the others in that big family tree of yours — that help determine the amount of melanin that is secreted. The genetics are somewhat complicated.
