Pour each color of candy melts into their own microwave safe bowl.
Microwave the candy melts for 30 seconds. Stir. Microwave for another 30 seconds and stir. The candy melts should be completely melted and smooth. (If not, microwave for 30 seconds and then stir.)
Line a baking sheet with a silicone mat or waxed paper.
Make dollops of each of the candy melt colors all over the prepared baking sheet. Use an offset spatula to swirl the colors together and spread the candy to the edges of the baking sheet. The less you can mix the colors the better. You want the colors swirled, not completely mixed together.
Sprinkle the top of the bark with chocolate shimmer beads, silver sprinkles, and gold disco dust.
Refrigerate the candy for 15 minutes, or until set.
Peel the candy off the silicone mat (or waxed paper) and use your hand to break into pieces.
Refrigerate until ready to serve.
Disco dust is optional. I liked the glitter effect it gives. If you prefer to not use disco dust, any gold sprinkle would work just fine too.
