The color's not the worst part, despite looking like something which had its colors run during an overbleached hot wash--it's the back. The back has these little yellow "20"s stamped over it randomly. It looks like some small child went crazy on the bill with a little "20" rubber stamp and then gave the bill to you, giggling in the hopes that you won't notice the enormously dastardly deed.
Furthermore, I don't even care what the currency looks like. People who actually do must be having a fit right now.
