sky blue, but the color around the middle of my eye changes to blueish green, blueish purple, and blueish grey. if 你 saw them 你 would think they're beautiful.
When I was little it used to change but now my eye colour is green and at the morning 或者 when there's a very bright light my eyes are green with 橙子, 橙色 colour in the middle... hard to describe xD
My eyes have three colours, the ring around them is navy blue then in the rest of them (other than the pupil obviously.) have a dark-ish blue and bright sky blue, it's really weird. :P
