Do they match the colors anywhere? like home depo?
I think most places colour match. I just went to WalMart because I knew they'd be cheap. When colour matching, only certain brand of paint will match perfectly, though.
Another option is to take you jersey and match it as closely to the wall of colours they have in store.
Could have just painted the room blue and green with some white stripes.... I guess it's just easier to staple crap to the wall - lazy ass.
Relax, guy. It's already been mentioned that he should paint it and it's already been mentioned that the room is a little cluttered. You don't have to be a d**k.
