Match the Color

'Subha' is a girl of 5 years old. Already she can recognize almost all of the colors and shapes even she can count till hundred. One day her father bought her a lot of colorful balls to play a game with her.
Her father placed some colorful balls as the following style-

After placing these, her father asked her to replace some balls to make all of them to same color. The only condition is to replace minimum number of balls as possible.

Subha did it after trying several times. She changed 5 balls and made all of them as color G. But she can't count more than hundreds, so it'll be difficult for her if her father asks her to solve such a problem with thousand of balls. But as I know you don't have any limitation of counting. So please help her to solve it.
