The main goal of ColorSpotter is to click on the color that shows in the background. The circle in the bottom of your screen shows a small list of colors and one of them is the correct color. If you guess it right, 1 point is added to your score. If you click on the wrong color, you lose and if you don't click on any color, 1 point is removed from your score and the colors show up again until you click.
Be careful! Every time you go to the next color, its much harder to click on the right color!
Have fun and don't forget to spot the right colors!
