Ingredients
10 hard boiled eggs
food coloring
1 tsp vinegar for each color you are using
water
½ cup mayonnaise or Miracle Whip or half of each (I use Miracle Whip)

Remove the shells from the hard boiled eggs and slice each egg in half.
Remove the yolks from the egg halves and place in a bowl. Set the yolks aside.
Get enough glasses or mugs for the number of colors you want to use. Fill the mugs or glasses ⅔ of the way full with cold water.
Add 3 drops of desired food coloring along with 1 tsp vinegar to each mug or cup.
Place egg whites in the mugs and allow to sit in the food coloring until desired color is reached. I could fit 3 egg whites in each of my mugs at a time.
Remove whites from dye and drain on a plate lined with a couple of paper towels.
Take the reserved yolks and mash them with a fork. Then mix in the ½ cup mayonnaise with the mashed yolk.
Pipe or spoon the yolk mix into the colored egg whites. Makes 20 deviled egg halves.
