Nice article from the BBC on what we can learn about the brain from visual illusions. In the picture on the right you can’t see the panther about to attack – but you can when viewed in colour. Which explains why colour vision is adaptive.

If your eyes follow the movement of the rotating pink dot, the dots will remain only one colour, pink.
However if you stare at the black ‘+ ‘ in the centre, the moving dot turns to green.
Now, concentrate on the black ‘ +’ in the centre of the picture. After a short period, all the pink dots will slowly disappear, and you will only see only a single green dot rotating.
It’s amazing how our brain works. There really is no green dot, and the pink ones really don’t disappear. This should be proof enough, we don’t always see what we think we see.
