Debunking the Myth: Bulls and the Color Red
For years, pop culture has popularized the belief that bulls hate the color red, leading to the imagery of matadors waving their bright red capes to provoke these mighty animals. But how much truth lies behind this belief? Let’s explore the origins of this myth, the science behind a bull’s perception of colors, and the real reason behind their aggressive behavior during bullfighting.
Origin of the Myth
The association between bulls and the color red traces back to ancient bullfighting traditions in countries such as Spain, where matadors have long used brightly colored muletas (capes) during their performances. As this spectacle evolved over centuries, the use of the red muleta became a symbol of the fight. With time, a widespread misconception emerged that the red color itself enrages the bull.
Understanding a Bull’s Color Perception
Contrary to the popular belief, bulls, like other cattle, are dichromatic, meaning they have only two types of color receptors (cones) in their eyes. According to a study in the “Journal of Experimental Biology,” cattle are likely to perceive colors in the blue and yellow range, but not in the red spectrum. This means that the red cape appears as a shade of gray to the bull.

In light of this, it is apparent that it is not the color of the cape that triggers the bull’s aggressive behavior, but rather its movement.
The Real Provocation: Movement, Not Color
When a matador twirls or flicks the cape, the bull perceives this as a threat or a challenge. Bulls, being territorial creatures, are prone to charge at moving objects as a defensive response. In the context of bullfighting, this aggressive behavior is further intensified due to the stress, loud noises, and the injuries inflicted upon the bull.
Research from the “Journal of Animal Science and Biotechnology” suggests that movement and contrasting patterns are more likely to catch the attention of cattle compared to stationary or uniformly colored objects.

Hence, a matador could wave a blue, green, or even a white muleta, and as long as it’s moved in a way that the bull perceives as a threat, the animal would react similarly.
In Conclusion
The myth of bulls hating the color red is deeply rooted in cultural narratives, overshadowing the scientific understanding of a bull’s perception and behavior. In truth, bulls cannot distinguish red from any other color, and it is the movement, not the color, that elicits their aggressive response. Debunking this myth not only broadens our understanding of these majestic creatures but also highlights the importance of basing our beliefs on scientific evidence rather than age-old traditions.
