Can identical twins have different hair and eye color and still be identical? Me and my twin sister are almost exactly identical in every way except our hair and eye color. I have blond hair and gray-blue eyes, and she has light brown hair and gray-green eyes. Our doctor says we are identical but no one thinks we are because we have different an eye colors. So if anyone knows if identical twins can be identical even if they have different hair and eye colors i'd love to know what you think. Update: we are both girls by the way.
Striking sisters couldn't be more different due to quirk in their mixed-raced parentage. One has straight ginger hair, a fair complexion and deep blue eyes. The other has masses of curls, far darker skin and her eyes are a sparkling brown. With such opposing looks itâs hard to believe this striking pair are sisters. But they are much more than that â they are twins. The girls were born with radically different colouring thanks to a quirk of their mixed-race parentage.
