Red rag to a bull is a myth, as the bull is colour-blind to red. It is the the waving cape that causes the bull to charge.
It makes no difference what the colour of the rag is the bull is enraged and will attack any thing that it can in order to protect it's self, red is just a good colour and it doesn't look as messy when it comes into contact with the bulls bloodied hide.
The bull chases the movement not the colour. The bullfighters cloak is traditionally red to a) hide the blood and b) part of the whole spectacle. But it is the origin of the phrase, "Red rag to a bull"
It means to stop drinking red bull
