1. In a large bowl, melt the dark chocolate until smooth. Keep warm, and set aside.
2. Divide the white chocolate evenly between 2 bowls. Add 1 tablespoon of coconut oil to each bowl. Melt until smooth. Add purple food coloring to one bowl and blue food coloring to the other bowl.
3. Line a baking sheet with parchment paper. Pour the melted dark chocolate on top, using a spatula to spread to your desired thickness.
4. Pour the blue chocolate over the dark chocolate. Then, add the purple chocolate. Use the tip of a knife to swirl the chocolate around until you get the desired look. Add sprinkles. Refrigerate for at least 1 hour before breaking into pieces.
