It's a lore thing. Though if you have to have them, you can go down into the face paint options and select it. It's basically indistinguishable unless you zoom right up into their face.

Doesn't matter, as long as Hyurs and Miqotes look good.
Only thing I'd really ask to add in that could easily be put in:
Give male Xaela the option to have white sclera. Even the female Xaela have normal white sclera, but for some reason, the males are stuck with medium/dark grey.
I'm hoping 4.x brings these things & more. With the death of PS3 there could be less burden on the servers (depending on how they implement/ed it) thus allowing greater variability.
