I don't know what to put for the poll because my eyes are a greenish-brown colour. I've been told in the past that they look more green than brown, but sometimes it kinda looks like they're more brown than green.
Mine are blue which I like a lot. They are somewhere between light and dark, with almost aqua tinge to them. The color is most noticeable on the edge of the iris. They also have tiny specs of brown throughout, and partly near the pupil.
