The flags of the U.S.states exhibit a variety of regional influences and local histories, as well as different styles and design principles. Nonetheless, the majority of the states' flags share the same design pattern consisting of the state seal superimposed on a monochrome background, commonly blue.
According to a 2001 survey by the North American Vexillological Association, New Mexico has the best-designed flag of any U.S. state, U.S. territory, or Canadian province, while Georgia's state flag was rated the worst design. (Georgia adopted a new flag in 2003; Nebraska's state flag, whose design was rated second worst, remains in use to date.) About half the flags have a common "seal on a bed sheet" design, wherein the state seal is simply put on a solid, usually blue, background. Such flags consistently get the lowest ranks from the Vexillological Association.
