Brain Exerciser,Comp. 9 colors

The rule is really simple, 9 panels with each color switched ON and OFF by tapping, but at the same time the panel that adjacent to each other in the up, down, left and right also will be switched ON and OFF. Please ON all 9 colors by combining this. The game will be one after the other questions, but let's answer to think well it does not matter to time score.
