Melt the pink candy melts according to package instructions and using the paint brush, apply a layer of pink chocolate in splotches all over the silicone baking cup.  Place the cups in the refrigerator to set while you melt the next color of candy melts.

Continue this with the remaining colors until the silicone baking cup is totally coated.  Place the cups in the refrigerator to set for 10 minutes.  Then repeat with all of the colors again.  When complete, refrigerate for an hour.  

When the chocolate is totally set, remove the silicone baking cup.  Store the cups somewhere cool or in the refrigerator until you're ready to use.  Fill the chocolate cups with your desired filling and serve.
