Bulls Are Color Blind
If Bull Are Color Blind then why do people associate them with seeing red?

Bulls are indeed colorblind. To a bull's eye, a red cape is a gray cape. The red cape, which inspired the phrase "seeing red," is purely a theatrical tradition. However, to a bull bred exclusively for aggressiveness, that flapping cape can prove very irritating. As this post from the Washington University Medical School astutely notes, animals bred for bullfighting are tested around the age of three for aggressiveness before they go into the ring. The orneriest ones make the cut. - From Dear Yahoo |
