NFPA 79 16.1.3 The use of other colors for the purpose of identification shall be as follows:
-BLACK: Ungrounded line,load,and control conducters at line voltage.

-RED: Ungrounded ac control conductors,at less than line voltage.

-BLUE: Ungrounded dc control conductors.

-YELLOW: Ungrounded control circuit conductors that may remain energized when the main disconnecting means is in the OFF position. These conductors shall be YELLOW throughout the entire circuit, including wiring in the control panel and the external field wiring.
NOTE: The international and European standards require the use of ORANGE for this purpose.

-WHITE or NATURAL GRAY: Grounded circuit conductor.

-WHITE WITH BLUE STRIPE: Grounded (current carrying) dc circuit conductors.

NOTE: The international and European standards require the use of the color LIGHT BLUE for the neutral conductor.

-WHITE WITH YELLOW STRIPE: grounded (current carrying) ac control circuit conductors that remain energized when the main disconnecting means is in the OFF position. For additional circuits powered from different sources that remain energized when the main disconnecting means is in the OFF position, striping colors other than GREEN, YELLOW or BLUE shall be used for the unique identification of the grounded conductors.
