Technically, the color red is used more for the audience's benefit in bullfights. It's the movement of the flag that really pisses them off (also, bullfighting bulls are usually castrated, but we digress). I don't think Adam's horns are bull horns, but goat horns. Goats, demons, etc. etc. That definitely explains his complete lack of morality, as well as the "Seeing Red" power.
