Put one color of candy melts in a microwave-safe bowl and microwave them in increments of 20 seconds. Stir in between. Remove once fully melted. You can also heat the candy melts in a small saucepan on low heat.
Carefully dip each pretzel in the melted candy (it will be hot) and then decorate with your favorite sprinkles. Lay the dipped pretzels on a parchment-lined cookie sheet to dry.
Repeat these steps for the other colors of candy melt.
Put the dipped pretzels in the fridge for about 30 minutes, or until the candy has fully hardened.
Store completed dipped pretzels in an airtight container.
