I have blonde hair (ashy). It's the kind that goes darker as you get older, but it's actually started to lighten in the last couple of years (I have a lot of white hair for my not quite twenty seven years).
I have eyes that change colour. They were blue until I was thirteen and now they're not. My eyes are currently (yes, I just checked) green with grey and yellow (the grey is sort of like a ring at the edge and the yellow is like small imperfect halo next to the pupil). My right eye has more yellow.
This is roughly what it is most of the time now, though the exact proportions of the colours change (if yellow is present, my right eye always has more. Sometimes, only my right eye has yellow).
Occasionally my eyes are a grey blue, or mostly grey or mostly blue. I think I've only seen my original eye colour once since it changed.
Three times I've been talking to people (once BF, the other two were friends) and they announced: you know, your eyes are changing colour... the last time, I dashed to the mirror, but I didn't get there in time, so I have no idea what that looks like, or whether it's constantly happening or happens mostly when I sleep.
I think it's a varient on heterochromia iridis/iridium.
But in a perfect world what would I look like - I'd have about two dozen wigs I think, and change my hair every day.
