My twins were both born with blue eyes, but one twin had lighter blue eyes and was fairer in general (skin and blonde hair). By six months I asked my ped if the fair twin was going to keep her bright blue eyes and she said likely yes, since they were so blue with no hint of any other color. Well, she is 2.5 and still has the bluest eyes and blondest hair. As for the other twin, by 6 months her eyes had turned from dark blue to green, and now they are hazel brown. Took awhile to completely turn! As for the hair, they were both born pretty bald so they had nowhere to go but gain hair. FYI, my husband is of scandanavian descent and has blue eyes and blonde hair. I have dark brown eyes and medium hair, but my dad has blue green eyes so maybe some of those recessives came out!
