What are the different colors on a standard electrical wiring diagram, and how do they correspond to the functions of white, neutral, black, and hot wires?

On a standard electrical wiring diagram, the colors typically used are white for neutral, black for hot, and sometimes red for hot as well. White wires represent the neutral wire, which carries the current back to the power source. Black or red wires represent the hot wire, which carries the current from the power source to the device being powered. It is important to follow the color-coding to ensure proper and safe electrical connections.
