Eyes are a big factor for me. But I don't have a favorite eye colour...
On some guys, brown eyes can be gorgeous, on others blue eyes are amazing! It really varies from one person to the next!
But eyes can reveal so much about a person. I don't know how but you can just get to know them a little better by seeing what kind of "twinkle" they have in their eyes. A mischievious one? A happy one? An ambitious one? Again, it varies from person to person!
Basically, don't get yourself down just because you don't have eyes of a certain colour! Eyes are an amazing feature on a guy but they can't be changed and will appeal to some girls but not others.
Yes. I love blue eyes on a guy. I fall so easily for tall dark haired blue eyed athletic guys but green and brown eyes are nice too. I consider eyes important because I see them the most on my guy but smile, athletisism and personality are big factors for me too.
