You are...
Risa!

In a word... Psychiatrist. You counsel your friends -- which is a good thing. Without you, your friends would most likely kill each other in an all-out brawl. You calm and mostly quiet -- but when you do yell, it's really, really, loud. Borderline scary. I mean freaky. Really. You're one of the more normal Loopers (if there is such a thing.) If I had to assign you a color, I would pick purple! Or maybe Light Urple... *shrugs* ^_^V
