But it doesn't darken the skin to pitch black. Luca says that she does not like dwarven fashion, so the implication to me is that all the dwarves are just shorter, darker skinned people who will look like Luca if they put on human clothes. At one point, Zangetsu wears dwarven clothes and has a blackened face, too.
