Literally the only time the skin-color thing registered with me was when we saw a flashback of Lyse's father in Stormblood, and I immediately concluded "Welp, she's adopted. Probably secretly the real heir to the Garlean throne or something." And it turned out (hopefully) that she's just inexplicably very white.

But then I made a black miqo'te. Not "appearing to be of African ancestry", but black-black. So what do I know?
