Honestly, they change colors. I was born with aqua-colored eyes, and somewhere around 6-7 yrs. old, they turned slate grey. They turned this bluish color around 10 years old, and they've been this way since. Depending on what color shirt I have on (and what color e/s I use), they look blue, grey or green. 99.9% of the time I'd say they're blue though. If you look at the pic in the body of my profile (not the profile pic itself), my eyes actually look green when you first look at the pic. I'll try to upload a pic of me from when I was in Kindergarten (if I can find the pic). My eyes were WAY more blue then!
