Here are the steps to color your hair naturally with coffee:

1. Brew a strong cup of dark-roast coffee; the stronger, the better.
2. Let the coffee cool to room temperature, and add 2 tablespoons of coffee grounds.
3. Add 1 cup of leave-in conditioner.
4. Wash your hair with shampoo.
5. With your hair still damp, apply the coffee dye evenly.
6. Let the dye sit in your hair for at least 1 hour.
7. Rinse your hair with water and condition it.

You can repeat this process if you want a darker color . I hope this helps!
