Color code

A color code or colour code is a system for displaying information by using different colors. The earliest examples of color codes in use are for long distance communication by use of flags, as in semaphore communication; the United Kingdom adopted a color code scheme for such communication wherein red signified danger and white signified safety, with other colors having similar assignments of meaning. As chemistry and other technologies advanced, it became expedient to use coloration as a signal for telling apart things that would otherwise be confusingly similar, such as wiring in electrical and electronic devices, pharmaceutical pills; the use of color codes has been extended to abstractions, such as the Homeland Security Advisory System color code in the United States. Hospital emergency codes incorporate colors, although they may include numbers, may not conform to a uniform standard. Color codes do present some potential problems. On forms and signage, the use of color can distract from white text.
