At first glance, the colored spots are virtually imminent. But concentrate on the small black dot at the middle. Stare at it for 30 minutes and you will slowly see how the colored spots slowly disappear. Try it! This is fun. The disappearing effect is one of the best optical illusion.

Great illusion. Spots disappeared after 1 minute. It has something with periphery sight.
