That's what people mean by gray eyes. I learned this a few years back. They don't actuallyook gray. My eyes are technically "gray" as well.

You probably have grey eyes then. It has shades of blue and green

Mine are similar, they're normally light brown but people tell me they look green sometimes when the light hits them at a certain angle.

That makes them hazel. Right?

Yeah mine do something similar but they are most certainly green on a normal day.

I think it's refraction off of shirts etc that give a bluish look

Same
