If you’ve ever flipped through a documentary or seen a snippet of a bullfight online, you’ve probably noticed the matador waving a bright red cape at the charging bull. It’s easy to assume the bull is furious at the color—but that’s a myth that’s been around for decades. Let’s dig into what’s really happening here, plus a few other common myths about bulls and bullfighting that need to be set straight.
The red cape myth: what’s really going on?
First things first: bulls have dichromatic vision. That means they only have two types of color-detecting cells (cones) in their eyes, compared to humans’ three. This makes them unable to distinguish between red and green—those colors look the same to them. So when a matador swishes the red cape, the bull isn’t reacting to the hue. It’s the quick, sudden movements that trigger their defensive response.
Researchers have tested this theory: if you wave a white or blue cloth in front of a bull the same way, it will charge just as aggressively. The red cape is purely for show—it’s meant to captivate the audience, not the bull. It stands out against the arena’s sand and adds drama to the performance.
Common myths vs. actual bull behavior
Let’s clear up some other misconceptions with a quick comparison:
| Common Belief | Actual Truth |
|---|---|
| Bulls hate the color red | Bulls are red-green colorblind; they react to movement, not color. |
| Bulls are naturally aggressive | Domesticated bulls are calm unless provoked (e.g., poked with sharp tools in bullfights). |
| Bullfighting is a fair contest | Bulls are weakened with barbed darts before the fight, giving the matador an unfair advantage. |
3 more bullfighting myths to debunk
Myth 1: Bullfighting is a “sport” of skill
Many proponents call bullfighting a sport, but it’s far from fair. Before the matador even steps into the ring, the bull is subjected to a series of painful attacks. Banderillas—sharp, barbed darts—are stuck into the bull’s back, causing deep wounds and bleeding. This weakens the bull, making it slower and more disoriented. By the time the matador arrives, the bull is already hurt, giving the human an unfair edge.
Myth 2: The final strike is quick and humane
The matador’s goal is to pierce the bull’s heart with a sword. But this doesn’t always happen. In many cases, the sword misses the heart, leading to a slow, painful death. Even if it hits, the bull may take several minutes to die. Animal welfare groups have long criticized this as cruel, and many countries are banning the practice as a result.
Myth 3: Bullfighting preserves cultural heritage
While some argue bullfighting is part of their cultural identity, polls show that a majority of Spaniards (where bullfighting is most famous) no longer support it. Several regions in Spain, like Catalonia, have banned bullfighting entirely. It’s not a universal tradition—it’s a practice that’s falling out of favor as people become more aware of animal cruelty.
What bulls are really like
Bulls are more complex than many people think. They’re social animals that live in herds and use body language to communicate—like lowering their heads or pawing the ground to show dominance. They also have strong memories: if a bull has a bad experience with a human, it may remember that person for a long time. Bulls also have a strong sense of territory; they may charge if they feel their space is being invaded, but this is a defensive reaction, not an aggressive one. On farms, bulls are often kept in large pastures where they can graze and interact with other animals—this keeps them happy and calm.
The next time you hear someone say bulls hate red, you can share the facts: it’s movement, not color, that gets their attention. And when it comes to bullfighting, the myths often mask the cruelty. As more people learn about the reality, the practice is slowly fading—proving that facts can change how we see the world (and the animals in it).
