It's important to never touch the prongs of a dryer cord while it's plugged in. Electricity is dangerous and can be fatal.

However, if you're asking about the standard color coding for wiring in a 4-prong dryer cord, here's the breakdown:

* White: Neutral wire

* Black: Hot wire

* Green: Ground wire

* Red: This is the fourth wire and it can be used for either a second hot wire (in a 240-volt system) or a dedicated ground wire.

Remember: It's crucial to consult a qualified electrician for any electrical work, including examining or working on dryer cords.
