PUZZLE WITH CHANGING COLORS

When you click, the squares in the upper-left corner are repainted in the specific color that you have chosen. Your task is, thus, changing the colors of an increasing group of squares, to achieve repainting of the entire playing field in one color. Each time you click on one of the six colors in the upper-left panel, the group takes on that color, absorbing the elements next to it.

It seems that everything is simple, however, the game has a limit on the number of moves. You may not need literally three or four moves to repaint the entire field, so be extremely careful and do not waste your moves in vain. For example, you should not repaint a group in red if it only consumes one or two squares. Instead, choose a color that will allow you to include more elements in the repaint. Use logic!
