For your eyes only!

If your eyes follow the movement of the rotating pink dot, you will only see one color, pink.
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 of time, all the pink dots will slowly disappear, and you will only see a 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.

Happy Deepavali!

Happy Deepavali to you too!!

Keerthi had a post on the optical illusion sometime ago. It is indeed really amazing..

The appearance of green while focussing on the black + is due to the 'complimentarity'. If you remove pink completely from white light, the remaining color is green!!

The disappearance of pink circles happens when the eyes get off-focus while concentrating..
Kanngalai nambaathey !!!

Vijay, thought this kind of made a good post for both 'Trick or treat' and 'Light & sound'!

Sen, thanks.

Raju, thanks for the wishes and for the explanations too.
