Rules of Color Codes
( According to Greg )

1. Always try to use the Beldon Color Code Chart Before using any other chart.  You can find it listed in the back of any Beldon Catalogue
2. Don't Use The Resistor Color Code Unless Absolutely Necessary (Some "rainbow" Ribbon Cable is an Exception)
3. The Darkest Color goes to the lowest potential signal.  (black is ground before green)
4. The Lightest Color goes to the highest potential signal.  (white is power before red)
5. When describing a 2-color wire, use the most predominant color then the marker or stripe.
6. There is no GRAY wire, it is SLATE  (The Abbreviation for GR might confuse someone to think Green)
7. The abbreviation for Green is GN  and not GR
8. The abbreviation for Blue is BL not BU
9. The abbreviation for Brown is BR not BN
10. There is no Purple wire, it is Violet  (VI)
