"Oh, butts," Isabel says. "I was sure I had it, too! At least this won't last too long." She still sighs, though. About a day's worth of vibrant blue hair isn't bad...save for the exact problem Noa has already touched on.

"It'd probably be all right if we were in primary colors, it's that orange that's really going to kill it." Because blue and orange were opposing on the color wheel. Blegh.

"I suppose using a guitar would've been better, but that's not as portable as this thing is, and the theory should be the same! I know how to read music..." She's only annoyed, not angry, but it's still frustrating. "Are you going to try it?"

Isabel does want to see if he can do her one better--but she also doesn't want him to end up in the same predicament, which is why it's questioning and not a flat out challenge.
