Eyes are so strange. Ever looked at your own iris through a magnifying glass? Mine are strands of grey, yellow and grey-blue... in different lights and settings they can appear more grey, more green, or more blue. They're hard to pin down as a colour and as I've aged they seem darker and sometimes the colours stand out more. I've also found different emotional states seem to make the colours different, I'm assuming this is to do with pupil size and how the iris is relaxed/tense/etc. In my life I've often had "your eyes are blue today", "they're more green today", and of course I don't see my eyes and really have to imagine how they look in that moment, in the light, the environment, with certain clothes, certain emotional states.
