Manchester United, Arsenal, and Liverpool are more successful than any other English Premiership clubs. All these clubs have red shirts. Do they intimidate their opponents by wearing red?. http://www.nature.com/news/2005/050516/full/news050516-4.html
If they did Real and Barca would collapse before the red teams and people would collectively say "Real Madrid who?"
Incidentally... scientific study has shown that men are most attracted to women who wear red or pink... ... and ... Women are most likely (by a large factor) to wear red or pink when at peak fertility (and hornyness) So... if you want to hook up with a particular girl... wait till she's wearing red/pink to make your move.
And to back this up, apparently Seeing the colour red can make your heart beat faster. Couple more red facts for you The red stripes on the United States Flag stand for courage. Chinese brides traditionally wear red wedding dresses for good luck.
Did some daft yank tell you that, Doc? The thirteen (red and white) stripes on the U.S. flag represent the original thirteen colonies that broke away from Britain.
The white bits on the flag are there to represent the french who settled in Louisiana. The blue canton represents how most of Florida will be underwater in a few hundred years. The white stars represent how Hollywood is ethnically non-diverse.
More proof red beats blue. Summary... in over 1000 games of first player shooters the players that were assigned red won a statistically significant amount of times more than blue. (What that means is: red won enough times that it is highly unlikely this is just down to random chance). This is perhaps more significant than sports team results that could have a cultural reason for reds beating blue.
