Don't really care, but the official response (from a Japanese only article I read from creator a while back). Someone literaly asked if she was black. They said she wasn't black and was drawn tanned to contrast with Raven who they made very pale.
Also they don't speak French, but French influenced the Heksvilian or what ever they called it. So you could say they are a imaginary race of distant french people XD.
