Shades of Grey: The Road to High Saffron by Jasper Fforde

In this book Jasper Fforde starts a delightful new series, set in a world where people are ranked by their ability to perceive color. As Eddie Russett (who's been banished to East Carmine ostensibly for a prank but also has revolutionary ideas about improving queuing systems) soon learns, however, all is not how it appears, and soon he must choose his alliances and friends carefully. Although you can see how dystopic this society is from a mile away, Fforde's unique sense of humor and love of the eccentric make his satire quite enjoyable--perhaps even better than the Thursday Next series.
