Let eggs cool until they are still hot but easy to handle.
Prepare one full food coloring bottle per 1/4 cup cold water for each color
desired and place in a cup. Crack a hard boiled egg all around, leaving the
shell on. Place each cracked egg in the food coloring mixture, take out and
let dry on paper towels. When the eggs are dry and cold, remove the shells and
serve them in a white bowl.
