I agree with Blitzkreig. Actually not just indoeuropeans have that kind of complexion. Arabs too. My uncle is an Arab, and he has arab ancestry all the way through, but he is blande haired and blue eyed. my other uncle has a fair complexion too (only dirt blond and blue eyes) only Dad has a rudy complexion and hazel eyes out of the brothers. (I myself have light brown hair and dark eyes, both not on my mom's side-though I'm not rudy).
there was also a legend about an arab named zarqaa' al-yamaamah. she lived in a now extinct tribe, and she was famous for her deep blue eyes, and piercing sight (she was before Europeans were even heard of in Arabia), hence her name, Zarqaa'
