A broken society needs a new form of government and order. The citizens of the Prism are sorted into different color groups. Each color is determined by the person's traits. Reds- Trill Seekers, Pinks- Romantics, Yellows- Innocent, Greens - Intelligent, Blues- Cautious, and Purples- Obedience. Before citizens begin high school they have to take a test that determines which color they are. After the test they move into their new color and leave their family behind to start their new lives. Everything is controlled, until the main characters realize that they have to go outside the Prism gates into the unknown to form their own society.
