To the right of each Puzzle Value is a square of color. This color can be changed for each value and will be displayed as the puzzle value text during the game.
To manipulate these colors, click on a color square:
You may either select a color box from the Preset Colors on the top of the screen, or you can Adjust RGB Values to customize your own Team Colors.
Click OK to use the color that you've made or Cancel to exit the Color Selector.
