A brief history of wiring color codes
It took until 1928 for wire color coding to make its debut. The National Electrical Code® (NEC) was the first to reference it, and today continues to set the standards for the electrical industry. Following a uniform color code makes it easier to assess electrical wiring, and ensure safety among licensed professionals and homeowners alike.
The NEC wire color coding standards
Though there are international wire color codes, the U.S. follows the National Electrical Code ® (NEC). The code is identified as NFPA 70 ® because the NEC is sponsored by the National Fire Protection Association. Though not a federal law (states can choose to adopt it), it is approved by the American National Standards Institute (ANSI).

What color is circuit 2?
Circuit 2 is BLACK, which means circuit #20 is BLACK. Starting to get it yet? The idea is to memorize the circuit number color of the first six circuits in a panel. BLACK, RED, BLUE – 1, 3, 5 and 2, 4, 6. The same goes for any other voltage coloring scheme you may encounter.
Can you figure out the color of a wire?
Yes, its actually quite simple. Divide any circuit number by six and you can figure out the color of a wire you need. And now I’m going to teach you to be a circuit number ninja without using a color coded wiring chart.
When using the rule of six, what is the first six circuits?
When using the rule of six you will reference the first six circuits, their phase and color. The most important thing to remember is this: If a number divides evenly by 6 then that circuit will be the same phase color as the number 6. If there’s a remainder, use that to determine the wire color. Example 1:
Is circuit #24 the same as circuit #6?
Since 6 divided evenly, circuit #24 will be the same color as circuit #6. Using the panel or layout above find what color circuit 6 is. Circuit 6 is BLUE, which means circuit number 24 is BLUE. Example 2:
