First, you will need to hard boil your eggs. Fill a pot with a couple inches of cold water, add the eggs, and then cover the eggs with cold water. 

Put the pot on the stove and bring the water to a boil. 

After the water is boiling, add a pinch of salt and a splash of white vinegar. Then, turn the heat off and put a lid on the pot. Let it sit for 12-minutes. 

While you're waiting on the eggs, boil a kettle. Then, fill each of your jars or containers with boiling water and 2 teaspoons of white vinegar. 

Next, add as much or as little food coloring as you prefer.

Once the eggs have sat for 12-minutes, allow them to cool completely before dying the eggs. 

Then, drop each egg one at a time into the jars of dye. Let them sit for 5-minutes to absorb the colors. 

Remove the eggs from the jars when they have reached a color you are happy with using tongs. 

Put your dyed eggs in an egg carton or on a paper towel to dry. 

Repeat the process for all the hard boiled eggs.

Have fun and enjoy!
