Green- when the question was easy. Orange - when I needed to do that problem twice. Pink - Needed to ask what it was because I had a doubt. Flouroscent yellow - when a question was extremely important. Blue - code for danger cause I could not make out what the hell problem was asking. It was mission abort. ***** Murphy had codes for the problems in her life. It made things easier for her. Like when she could not understand any question in chemistry it was usually pink. Or when her parents left her with her aunt because they could not bear to see her face, it was flouroscent yellow. Or when she is dropped in a new school three months into her last year, it was blue. Or when she gave too many sweets to Arizona, ( accidentally of course ) then it is code blue. But she does not know what colour to appoint when one of the heart-throbs of school takes a sudden interest in her and won't leave her alone. It was surely worse than blue.
