I'm hoping that in 4.0 we could possibly get an option to make our eyes more brightly-colored. Right now a lot of colors look a lot more darker than I think they should (more or less depending on race). And even if you do go for a lighter shade of a color, it just looks watered down. I'm not necessary asking for something like Au'ra's limbal rings, i'd just like to see if the colors we have now can pop out a bit more.
