Line a baking sheet with wax paper to prepare your workspace.
In separate microwave-safe bowls, melt each color of chocolate melts in 30-second intervals, stirring between each, until smooth.
Dip each mini pretzel into the melted chocolate, ensuring an even coating. Let excess chocolate drip off before placing it on the wax paper.
Arrange five coated pretzels in a circle on the wax paper, with the bottom points touching to form flower petals.
While the chocolate is still wet, place a yellow chocolate melt in the center of each flower.
Let the pretzel flowers sit at room temperature until the chocolate hardens completely.
Once set, serve immediately or store in an airtight container for later.
