Bulls are attracted to the color red.

The story behind the answer

False. Bulls aren’t enraged by red—they’re largely red-green color-blind. Like many ungulates, cattle have two types of cone cells (dichromatic vision), so a bright red cape appears as a dull gray. What actually triggers a bull’s charge is the rapid, sweeping motion of the matador’s cape and the animal’s arousal during the event.

Why the red cape, then? Tradition and practicality: the red color helps mask blood and adds theatrical flair for spectators. To remember: it’s the motion, not the color. This myth highlights how animal behavior is driven more by movement, threat perception, and context than by hues humans find dramatic.
