According to "MythBusters: Red Rag to a Bull," this myth has been BUSTED.
An 1,800-pound bull can hook a grown man with his horns and toss him 30 feet in the air, so the MythBusters set out to find a way to test this myth—carefully. They decided to put makeshift matadors into an arena, each holding a flag of a different color, and wait for an angry bull to see red.
Bulls don't seem to have any color preference at all. They'll charge whichever object is moving the most, which means this old myth can get tossed out right out of the ring.

Spanish matadors began using a small red cape, or muleta, in bullfighting around the 1700s. Ever since, it seems, people have perpetuated the color-charged myth that red makes bulls go wild.
