A '''color code''' or '''colour code''' is a system for displaying information by using different [[color]]s.

The earliest examples of color codes in use are for long distance communication by use of flags, as in [[Flag semaphore|semaphore]] communication.<ref>''Transactions of the American Society of Civil Engineers: Volume 29'' (1893), p. 507.</ref> The [[United Kingdom]] adopted a color code scheme for such communication wherein [[red]] signified [[Risk|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 [[Electrical wiring|wiring]] in electrical and electronic devices, and pharmaceutical [[Pill (pharmacy)|pills]].
