Social class and occupation

Blue may denote the working class, derived from the traditional color of factory uniforms. Blue-collar workers are industrial workers and are often contrasted white-collar office workers. However, in contrast to "blue collar," the phrase "blue blood" is used to mean "from an aristocratic background," because pale, untanned skin–a sign of notablity–allows blue-tinged veins to show through.

Several vocations are associated with blue. Law enforcement, and uniformed police, often wear blue uniforms and have become associated with the color, as seen in phrases such as "boys in blue," "blue line," and "blue wall." Most police cars have blue colors, and United Nations peacekeepers are uniformed in blue and white. "Bluecoat" (akin to "redcoat") refers to a uniformed police officer. Police in the People's Republic of China changed the color of their uniforms from green to blue in the late 1990s, partly to emphasize their civilian role. Since laws prohibit police from declaring a strike, the "blue flu" is a "sickout": a type of strike action in which police call in sick.
