Switching colors

I have an animation of THREE balls.
I have only TWO colors in my palette.

First ball is green.
Second ball is blue.
Third ball is also blue.

How can I easily switch a color of the second ball (blue) and make it the same color as the first one (green)? Please, notice that I can’t just change blue into green in my palette because I still want the third ball to be blue.

I hope there is a simple solution in TB Essentials.

Using the Repaint Tool you can repaint the second ball currently blue with green.

I am Agree with ampy .Repaint Tool is best for you.
