Line a baking sheet with wax paper to prepare your workspace.
In separate microwave-safe bowls, melt each color of chocolate melts by heating in 30-second intervals, stirring in between, until smooth.
Using a fork, dip each mini pretzel into the melted chocolate, ensuring an even coating. Let excess chocolate drip off before placing the pretzels on the wax paper.
Repeat the process with different chocolate colors to create a variety of pastel-coated pretzels.
For extra decoration, drizzle different colors over the pretzels using a fork.
Let the pretzels set at room temperature until the chocolate hardens completely.
Once set, serve immediately or store in an airtight container for later.
