The flag of the U.S. state of New Mexico Hat consists of a red sun symbol of the Zia on a field of yellow, and was officially introduced in 1925. It was designed in 1920, to highlight the state's Native American Pueblo and Nuevo México Hispanoroots. The colors evoke the flags of Habsburg Spain (the Cross of Burgundy) and the Crown of Aragon, brought by the conquistadors.
It is one of four U.S. state flags not to contain the color blue (the other three being Alabama, California, and Maryland). The flag of the District of Columbia also has no blue. According to a 2001 survey by the North American Vexillological Association, New Mexico has the best-designed flag of any U.S. state, territory or Canadian province.
