I don't think the color matters as much to me as just, the way they look I guess haha. I don't know how to explain it. But even when 2 people have the exact same eye color, it looks totally unique with them, since they can show a lot of your personality.
I think colored eyes like blue and green catch my attention more, because you don't see those as often around here, but I've seen amazing eyes in all colors haha :]
For breeding purposes brown. because people with brown eyes can see the best. that why most people have brown eyes. But I know what you mean green and blue.
I am a sucker for a great pair of bright blue eyes. They can pierce their way right through me. But at the same time, the great thing about eyes is how a woman uses them. The right kind of eye contact from the right woman will drive a man wild.the color doesn't matter. She can tell you exactly what she is going to do to you without using a single word with one single look.
