The background grid is one color and the user clicks the balls that are that color.
the background shifts through the colors on the screen, hitting the ball when the right color is present.
Click the balls in rgb order, if the game starts in blue then click blue first then go to green red etc.
The game also stores what colors you are most accurate at and determines what is your strongest color and your weakest color.
