TRY 3 Steps...もう私はピンクが緑に見える謎が分かりません・・・・・・・
1. Follow the movement of the rotating pink dot with your eyes. You will see only one color - Pink.
2. Now stare at the black "+" in the center, and the moving dot turns to green.
3. Now keep staring at the "+", and after a short time, all the pink dots disappear, and all you see is a rotating green dot!
