Shiro's hair is white, and his eyes are golden-brown.

Only when emotional or his Semblance is active does his black 'stripes' appear and his eyes change from golden-brown to hazel. Then ultimately/finally to a glowing icy blue.

Actually I've been meaning to ask, why is that? Don't get me wrong it's badass and everything but is it like a genetic trait, part of his semblance, a manifestation of his aura?
