  Yes, the eye color has been decided since the germ cell was formed. But the eye color of a newborn may change overtime, because the melanin inside his iris grows with time. As a result, the pigmentation of his eyes grow darker and deeper. So, the eye color only darkens with time. The eye color of a baby won't be set until at least the ninth month or when he is one year old. That will be the final color of his eyes.
