20-pair Colour Code (Australia)
The 20-pair colour code is a colour code used in Australia to identify individual conductors in a kind of electrical telecommunication wiring for indoor use, known as twisted pair cables. The colours are applied to the insulation that covers each conductor. The first colour is chosen from one group of five colours. The combinations are also shown in the table below showing the colour for each wire ("1" and "2") and the pair number. The Australian standard specifies "Grey" in Tables B2 to B7. There are systems in other countries where "Slate" is used rather than "Grey". This is perceived as a minimisation of confusion between "Green" and "Grey" and their potential abbreviations: "G", "Gr", or "Gre". No such consideration is made for "Black", "Blue", or "Brown", or their potential abbreviations of "B", "Bl", or "Br".

Colour Code
A color 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 Flag semaphore, semaphore communication. 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. The use of color codes has been extended to abstractions, such as the Homeland Security Advisory System color code in the United States. Similarly, hospital emergency codes often incorporate colors (such as the widely used "Code Blue" indicating a cardiac arrest), although they may also include n ...
