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.
Splatter until your heart is content!

Notes
Consistency is everything: Thick ribbons splatter beautifully; watery frosting just runs.
Add water ¼ teaspoon at a time — a tiny bit goes a long way.
Too thin? Add powdered sugar a tablespoon at a time to bring it back to a ribbon.
Gel food coloring gives the boldest color without thinning your paint.
Let each color set a moment before layering the next so they stay crisp.
