chunk: As the townsfolk become more colorful, a ban on "colored" people is initiated in public venues. Eventually, a riot is touched off by a nude painting of Betty (painted by Johnson) on the window of Mr. Johnson's soda shop. The soda shop is destroyed, books are burned, and people who are "colored" are harassed in the street. As a reaction, the town fathers announce rules preventing people from visiting the library, playing loud music, or using paint other than black, white, or gray. In protest, David and Mr. Johnson paint a colorful mural on a brick wall, depicting their world, prompting their arrest. Brought to trial in front of the town, David and Mr. Johnson defend their actions, and their passion begins to influence the non-colored members of the population into becoming colored. David also eventually arouses enough anger and indignation in Big Bob that the mayor becomes colored as well. The mayor runs off, effectively ending the segregation.
