First-ever images of living human retinas have yielded a surprise about how we perceive our world:
Colour perception is not in the eye of the beholder: it’s in the brain

Researchers at the University of Rochester have found that the number of colour-sensitive cones in the human retina differs dramatically among people — by up to 40 times — yet people appear to perceive colours the same way.
The findings strongly suggest that our perception of colour is controlled much more by our brains than by our eyes.
- “These experiments show that colour is defined by our experience in the world, and since we all share the same world, we arrive at the same definition of colours.”
