I'm afraid that sounds too weird to be true. Green has LESS pigment than brown. And some very little children have hazel eyes. But if anyone has the scientific reasons why this isn't so, pleas post! Everyone on my Mom's side has blue or hazel eyes, on my Dad's side, all different shades of brown, unless someone lucks out with a bright blue occasionally, or a golden-brown hazel. I can see how lightening up brown would produce a golden color or hazel. There is the color green in brown always, but not necessarily brown in green. But that is from an artist's viewpoint, maybe physically it is different.
I read on MSN recently that blue eyes (and blond hair) are a mutation: everyone thousands of years ago had different shades of brown hair & brown eyes. I'll try to find that article.
My Godmother's eyes turned a blue color from dark brown due to her eyedrops for glaucoma. She's not too jazzed about it, though, she'd rather not take the drops.
