Red, White, and Blue Bots

In the future, all the beautiful Washington, DC buildings will be covered with a special nanobot paint that can change colors through computer commands. One day, the mean nanobot, McHugh, decides it's time to change the nanopaint from white to many different colors. The citizens become upset and want the buildings put back to white. But it was not as easy as the citizens think until Nano and Nana come to the rescue.
