Animals and colour vision

Our brain decides, with the aid of previous experience, what we are looking at. This process is called perception.

Many animals can see in colour. How good this colour vision is varies from species to species. To see in colour the eyes must be able to respond to different wavelengths of light and send appropriate signals to the brain which then interprets this information.

All plants and animals respond to light, but to see there must be a means of detecting that light.
The eye of most animals contains an optical system that produces an image of the world on to a large number of light detectors.

Although we detect light with our eyes we see with our brain. The light signals received by our eyes are interpreted by our brain.
