I can't decide! I've thought about it a lot because eyes are my favorite feature! I guess it just depends on how you use them girls... ( I think I may be partial to gray or brown though... I'm not sure lol)
Unique eye colors always go to the top. Things like flecks, bands, etc. really make someone's eyes stand out. As for the "base" color, I think it's less important than the details (the things I mentioned above).
I knew this guy that when he was upset his eyes went this amazing black, silvery grey those were like :O. I think the prettiest eye colour is a mixture or eyes that change colour. My eyes are hazel and blueish.
well my eyes are pale and they are sometimes blue grey and sometimes a relle light green but usually the bluer color :)
