Using one small bowl for each color, add ½ cup of powdered sugar to each bowl.
Add ½ teaspoon of water to start & the food coloring of your choice and mix until smooth.
Depending on the amount of food dye needed, you may need to thin out your splatter paint frosting with ¼ teaspoon of water at a time or until thick ribbons form.
When mixing, If your paint gets too thin or drippy add 1 tablespoon of powdered sugar at a time until you get back to a thick ribbon-like consistency.
