Bulls aren't enraged by red. Cattle are red-green colorblind and barely see red. A bull charges a matador's muleta because the cloth moves, not its color. In MythBusters, bulls charged red, blue and white flags alike. Red just hides blood.
Yi Hwang (Toegye), a great Confucian scholar of the Joseon dynasty, found his white mourning robe patched with red cloth by his mentally ill wife. He wore it to the funeral anyway, telling mourners: "Red wards off evil spirits—my wife meant well."
