Why are we able to see colour?
The retina of our eye is covered by millions of light-sensitive cells, some shaped like rods, and some like cones. There are three types of cone-shaped cells, each sensitive to the long, medium, or short wavelengths of light which represent the colours red, green, and blue. These cells, working in combination with connecting nerve cells, give the brain enough information to interpret and name colours. In short, the human eye and brain together, translate light into colour.
