# Are bulls angered by the colour red?

> No. Cattle are dichromats and do not see red the way humans do. In bullfighting it is the movement of the cape, not its colour, that draws the charge; red is traditional and hides blood stains. Bovine colour vision is based on two cone types, not three.

## Key takeaways
- Cattle do not have human-like red sensitivity.
- Movement of the cape matters more than colour.
- Red tradition in bullfighting is cultural, not a sensory necessity.

## Answer
Bovine colour vision is based on two cone types, not three. Reds and greens are poorly distinguished compared with human vision. A still red object is not a reliable trigger.

Matadors use a moving muleta. Handlers with capes of other colours can elicit the same response when the cloth is flourished. The animal is reacting to motion and provocation in a confined arena, not to a wavelength.

The red-cape story persists because it is simple and visual. The biology is simpler still: move a large object in a bull’s face and you will get a reaction regardless of dye lot.
