If your eyes follow the movement of the rotating pink dot, the dots will remain only one color - pink.

However if you stare at the black “+” in the center, the moving dot turns to green.

Now, concentrate on the black “+” in the center 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.
