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.

You have a 3 way switch. Your black wire is the hot wire. Your green wire is the ground wire. Your red and white wires go to the light and other switch. You should have gotten a wiring diagram with your switch.
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. The red wire serves as the hot wire that carries electricity to the switch, allowing it to control the flow of electricity to the connected device. It is essential to follow proper electrical codes and guidelines when working with red wire switch legs to ensure safety and proper functionality.
How do you install a doorbell with four wires both having black and red wires?
It depends on what the wires are connected to and where the power supply is located. If the switch is lighted power has to get to the switch for the light. With a lighted switch you have a hot supply side, a neutral and then the wire going to the bell. So if Black 1 and Red 1 are supply voltage you would connect Red 1 to the hot side of switch, Black 1 would go to common as would Black 2. Red 2 would go to Bell side of the switch.
How do you wire a light switch with only black and red wires?
The black wire is typically the hot wire that carries the electrical current, while the red wire is often used as a traveler wire. Connect the black wire to one terminal of the light switch and the red wire to the other terminal. Make sure to turn off the power before wiring the switch to avoid electrical shock.
How can you wire a 3-way switch using only 12-2 wire?
To wire a 3-way switch using only 12-2 wire, connect the black (hot) wire from the power source to the common terminal of the first switch. Then, run a 12-2 cable to the second switch, connecting the two traveler terminals of the first switch to the two traveler terminals of the second switch using the black and red wires. Finally, connect the common terminal of the second switch to the light fixture, and ensure the white wire is properly connected as a neutral back to the fixture. Remember to use wire nuts and ensure proper grounding.
How to install a light switch with 3 wires correctly?
To install a light switch with 3 wires correctly, first turn off the power to the circuit. Connect the black wire to the screw terminal marked "common," the white wire to the screw terminal marked "neutral," and the red wire to the screw terminal marked "load." Secure the wires with wire nuts and then attach the switch to the electrical box. Turn the power back on and test the switch to ensure it is working properly.
How should I connect the red wire to the light switch?
