"I like pretty much all shades of blue." He laughed softly, pushed his free hand up to pat at his head. "Originally it wasn't that big a deal, you know. I mean, it was my favorite color, but I wasn't quite so into having everything be that color. But then I did my hair - and it wasn't meant to stick, but it did - and it became... sort of a joke? Then before I knew it, it just became part of who I was."
He shrugged his shoulders, squeezed Itachi's hand, and steered him a little toward a stand he thought he'd seen lollipops at.
