Are bulls color-blinded

Answer 1

Yes bulls are colour blind. Since the seventeenth century fighting bulls have been bred on bull ranches. They go through several selection processes during their first three years, in which only those with the best stamina, courage, appearance, and coloration are selected for eventual combat.

Bulls never receive realistic in preparation for combat. This is because they must, for symbolic reasons, be virginal regarding actual fighting experience. Also, because of their excellent memory, experienced bulls would be apt to develop tricky tactics rather than react just on the basis of raw courage and instinct as is expected.

Like all other fighting bulls are colour blind. The myth that a bull can see the colour red, is just that, a myth. Despite most bull-fighters using a red cape to attract the bull, the fact is that they could use a multi-coloured cape and the bull would still charge at them. The bull is only attracted to the movement of the cape, not the actual colour of it.

So technically the color red doesn't do anything. Its the movement from waving the flag around that angers them.

Answer 2

Not completely. They are dichromatic, where they can only see the prime colours of yellow and blue.
