Liz Taylor's eyes were dark blue, rather than violet. Violet only happens in people with albinism, though there is an urban myth about "Alexandria Genesis", which purportedly led to violet eyes, no periods, and no body hair. However there have been no confirmed cases of it, and all claims are completely unsubstantiated.
Something like that. I remember reading about it being made up for some fiction somewhere, but I can't find that source now. I remember it being on wiki for a while, occasionally I think someone edits it in for a joke, before the mods take it out again.
I actually have this really cool mutation in my eyes that make them two colors (called heterochromia) So My eyes are green with hazel rings (kinda) so at all times my eyes look green, but on fire.
This is what my eyes are, as well as my dad and my son. I just never knew it had a name. We all 3 have central heterochromia. Green with brown ring. Sweet.
google it.
