The truth is bulls do not hate red. Unlike humans, who can see every color, bulls cannot see the color red. Their sight cannot see the color red. Similar to other cattle, bulls lack the retina receptor needed to detect the pigments that make up the color red.

No, bulls do not hate the color red. They are actually color-blind to red. The common misconception arises from the sport of bullfighting, where the matador’s red cape is thought to anger the bull. Bulls, similar to other cattle, are dichromats, meaning they can only perceive two color spectrums – blue and yellow.

Do Bulls Hate Red? Many people think that the bulls blame the red fabric because they hate red, but the truth is that the bulls don’t care about the color. In addition, red has little effect on the behavior of the bulls. In fact, bulls, like healthy people, are moderately colorblind, therefore they can’t recognize the color red.

So does the color red make bulls angry? To put it simply, the answer is no! Instead, it’s because of the aggressive whipping of the cape. The reason why red couldn’t possibly be what makes bulls angry is that they can’t even see the color, since their eyes lack L-cones – the cone cells associated with detecting the color red.

We discovered that like all other cattle, bulls are actually red/green colorblind – meaning that the color of the muleta cannot be what angers them. Rather, it seems to be the movement of the cape that angers them. The muleta is believed to be traditionally red because the red color helps conceal the bull’s blood.
