Break out a muffin tin or empty egg carton.
Spoon some cold cream into the tin or carton. The amount you use is up to you. It will depend on how much paint you need in the end.
Mix 1 to 2 drops of various colors food coloring into each cup. Feel free to mix colors to create your own hues.
Decide which colors you want to paint with and find a powdered drink mix that matches that color.
Empty the different colored powdered drink mixes into their own cups. If you're feeling adventurous, mix some of the colors together.
Add 2 tbsp. of warm water to each cup and stir until completely mixed. The paint's now ready to hit the paper.
Choose a dry pigment to make into paint. Put a small amount onto a flat surface.
Use a palette knife to make a hole in the center of the pigment.
Pour a little water into the hole. Too much water will make the paint runny, so start with a very small amount of water and add more as needed.
Blend the water and pigment together with the knife. You want to create a smooth, evenly distributed paste.
Add the paste to a water-based paint binder. You can choose between acrylic, casein, egg tempera, watercolors or gouache. You can also use the paste to tint plaster or concrete. Now you're ready to paint.
