Have all of your sprinkles ready. Lay out a silicone baking sheet or parchment paper to make the bark on.
Heat the candy melts, each color in separate bowls, as per package directions. Heat them at the same time as much as possible so one does not get hard while waiting for others to melt.
When the candy melts are melted, spoon each color in alternating spots on the silicone baking mat. Continue until all of the candy is used, not leaving any gaps.
Use a knife or spatula to swirl the colors together as much or as little as desired.
Immediately top the candy with sprinkles as desired.
Let sit until the candy has hardened. Break the bark into pieces.
