It's just for show. Bulls are colorblind.
Bulls and cows are actually red green colour-blind. It is the annoying waving of the cape that causes the bull to charge in a bull-fight arena.

It is just a tradition that the cape is red. Some say that it is red because it is believed that the colour red angers bulls but since cattle are colourblind this cannot be true. Some say that the cape is red so that if it get bloody it does not show.
Traditionally, matadors wave a red cape at the bull. The bull is supposed to get angry at the color red, making him charge the matador. In reality, the bull does not care what color the cape is. He will charge a cape of any color.
The muleta (cape) is red but it is not the red color that attracts the bull, it is the motion of the cape, Bulls are red-green colorblind.
