Mercedes hair options after creation?

How about face and skin color? Please tell me i can have a Dark Elf.

If you mean after creation, I'm pretty sure you can change anything.

I've seen a few screenies of Demon Slayer with a more normal skin color, so I think at least that class has skin options.

You can choose between the purple-ish one or the normal white one. The other change-able option is the face patterns.
