Green is not color
In about 2005, at Duke West, people Screamed "GREEN IS NOT A COLOR!!" At quadfest, there are four teams. Red, yellow, blue, and green are the teams. Green is the only one that is not a primary color so that is why people scream that. In 2009, the cheer "green is not a color" by the Grellow team, soon turned into "Truman's not a color!"
