Summary: Electrical wire colors for most typical home electrical wiring. The chart below includes UK electrical wire, EU electrical wire, Australia electrical wire, New Zealand electrical wire, South Africa electrical wire, Canada electrical wire and United States electrical wire.
The Electrical Wire Identification System
To enable wires to be easily and safely identified all common wiring safety codes follow a structured color scheme for the insulation of electrical wire.
There are local rules and exceptions that exist based upon the exact application.
Many older wire installations may vary in color codes, and color may fade or change with heat and age of insulation.
such as Extension cords, power (line) cords and lamp cords

The Safest Way to Test Electrical Devices and Identify Electric Wiring!The Non-Contact Electrical Tester
This is a testing tool that I have had in my personal electrical tool pouch for years, and is the first test tool I grab to help identify electrical wiring. It is a Non-contact tester, [amazon.com], I use for the detection of Standard Voltage in Cables, Cords, Circuit Breakers, Lighting Fixtures, Switches, Outlets and Wires. Simply insert the end of the tester into an outlet, lamp socket, or hold the end of the tester against the wire you wish to test. Very handy and easy to use.
