Question

discuss about colour codefication​

Answer 1

Answer:

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.[1] 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, and pharmaceutical pills.
