Egg Yolk Paints

I use the food coloring pastes but liquids will work too!

1 egg yolk
1 Tbsp. warm water
paste color of your choice

Combine yolk and warm water, add color of your choice. Remember to wear gloves. It works best to use toothpicks to transfer the color concentrate to the yolk mixture.
Use a clean paint brush - any size you feel comfortable with. You may also dust with colored or plain sugar on top of the painted area as well.
