Yes, it happens to me a lot, not sure why. Maybe it's hazel? I've been told I have green eyes and have been told wow, your eyes just turned to a blue/grey. They have also been just blue or violet. I guess it may be a combination of the light, my clothing color and my mood? I can't look in a mirror long enough to see my eyes though so I have to go with what people say. When I've tried to look, I usually lose time and end up somewhere else...
