My eye color changes due to my shirt color... blue shirt: blue eyes. Green shirt: green eyes. Gray shirt: gray eyes. No shirt: blue-green eyes. Shirt with out blue, green, or gray: blue-green eyes. Can anyone help explain why my eye color changes like that?

That does happen to some people. I forget why. I knew a girl whose eyes constantly changed a lot of colors.

The main reason these sites seem to claim is moods.

I never tried seeing how mood affects it, I'll observe my moods and see if that's another reason
