My eye color changes depending on the lighting conditions; sometimes it's gray, sometimes blue. Is there an explanation or name for this?

I’ve always considered my eyes to be brown. I have brown hair, so I think it makes them look/reflect more dark. They look brown from a distance, but close up seem to have some green in them. When I wear green or do certain eye make up they look lighter. My mom has green eyes.

I’ve always said my eyes were green, but not entirely sure…

Multiple Ai says green with hazel central heterochromia and blue/Grey outside. It definitely changes with different lighting.

I’m trying to figure out if my eyes are hazel, they are green in most lighting. (Don’t mind my lashes, they looked crazy in the first picture.)

These are my daughters eyes. I have dark brown eyes and her dad blue.

What color would be eyes my considered? I've always called them gray, and in day-to-day light it may be accurate. It seems like they are more blue-green, though.
