hey ladies what color do my son's eyes look ?? everyone keeps telling me different colors lol some say blue some say green some say gray. he was born with blue eyes than around 10 months they would go between blue a really dark green and a green I've never seen before. He's now almost a yr in a half and to me they haven't turned blue or gray Since. college is his eye color from May July and August than the bottom is from last night.
