Green Eyes

[KGarrad]

There is also:
Amber eyes

The amber eye colour is often confused with hazel eyes, however, it is actually very rare. About 5% of the population is thought to possess this eye colour. Amber eyes are usually yellowish-brown in colour; sometimes they may even appear golden or orange in colour. The reason they are this colour is because they contain a large amount of yellowish pigmentation called lipochrome.

  I have green or greenish eyes, but most of the family have blue. My mother was rather peeved about a description, possibly when she joined the WAAF; light brown hair and blue-grey eyes. She thought it was very boring! There is a strain of red hair in the family and I always wished I had the red hair as well as the green eyes and pale, freckly skin.

I read some anthropology that said that 10,000 years ago all humans had brown eyes. All other colours are due to ancient genetic mutations.

Will climate change affect eye colour ?
