[Nightmaren]

White hair, pale skin, and pink eyes. If it is an older society, he would be cast out, so your character could react oddly. But again, the hood hides his face, so being slouched over and looking like an old man, that would be hiding his eyes, and so the odd appearance wouldn't affect you much at first. But if he were to go out among others without that disguise, he still keeps his bangs, and charcoal and soot could cover his hair, or mud perhaps, enough to look like a worker or something and get rid of most of the off hair color. Perhaps look like a slave or something as well. As for reasons, the character is often something like a kleptomaniac or someone who likes confusing or deceiving others, so on his spare time, visiting the town dressed as an old man to sneak items or peddle or beg for coins would amuse him.
