In reality, bulls do not hate the color red; it's a common misconception related to bullfighting (corrida de toros). In bullfights, the bull is often seen in an arena where the matador waves a red cloth (known as a muleta) to attract the bull's attention. However, bulls are not actually attracted to the color red, but to the movement of the cloth.
Bulls do not perceive colors in the same way humans do. They mainly see colors in shades of blue and gray, and the color red does not have any special effect on them. In bullfights, the red cloth is often used because it helps conceal bloodstains and is considered aesthetically pleasing in traditional rituals. The bull's excitement primarily comes from the movement of the cloth and changes in the environment, not from its color. The bull is stimulated by the movement and actions of the matador, which provoke it to charge.
History and Tradition
Red cloth has been used in bullfighting for a long time, but not because it makes the bull angry. On the contrary, the use of red is mainly symbolic and aesthetic. This tradition has existed since the 18th century in Spain and other countries with a bullfighting culture.
So, the truth is that bulls do not hate the color red; they simply react to the movement of the cloth during the fight.
