so I'm looking for a Dan and Phil book where it's basically like if you're feeling sad, you go blue and that kind of shit, and it's like Dan and Phil don't like each other and they're about to fight when they both glow pink or something which shows that they both like each other. I'm trying to find it but I can't and I don't recall who wrote it or what the name of it is. if anybody recognizes it, tell me PLEASE
