Typically the white wire is "neutral" and colored wires are power.
In a light switch, it depends on what the electrician wanted to do. Most use white for common and colored wires for travelers, but don't count on that. Switch legs often are wired a little differently, depending on the electrician.
If an electrician is being nice to you he will often put colored tape on a wire to indicate what he is doing, but it's not required.
If you have questions about the wiring, contact a qualified electrician to help with the problem.

How do you rewire an electric awning switch with red white black and green wires?
To rewire an electric awning switch with red, white, black, and green wires, first ensure the power is turned off to avoid electric shock. Typically, the black wire is the hot wire, connecting to the switch terminal marked for power, while the red wire may be for the awning motor. The white wire usually serves as the neutral, connecting to the terminal marked for neutral, and the green wire is typically the ground, which should be attached to the grounding terminal. Always consult the specific wiring diagram for your awning model to ensure proper connections.
What is a red wire switch leg?
A red wire switch leg is a specific wire used in electrical wiring to connect a switch to a light fixture or another electrical device.
