[QUOTE="sophia, post: 330395, member: 234326"] Also coming back to colour blindness in animals; this time focussing on the bull. For a long time it's been said that bulls were atracted to red so that's why, in a bullfight (very famous in Spain and a bit less in Portugal, although I personally dispise them) the bullfighter in the arena uses a red cap. Although many persons still believe this idea, it has been contradicted, precisely with the theory that bulls are in fact colour blind and have no sensitivity in colours. What in fact annoys the bull is the movements of the cap and not it's colour. I suppose that should be easy to prove: just try and move a blue or yellow cap in front of a bull ... and see for yourself what he does...:-rofl2 [/QUOTE]
