To make the blue dye, chop half of the red cabbage and add to a small saucepan and cover with 3 cups of water bring a low simmer for 25- 30 minutes. Strain and allow to come to room temperature. Add 2 tbsp of vinegar to the dye and mix.
Add enough of the dye liquid to submerge an egg to separate drinking glasses or ramekin dishes.
Submerge a white hardboiled egg in the blue dye for at least 2 hours for a light blue egg. Leave the egg in the dye overnight for a dark blue egg.
For the Yellow Easter Eggs
In a separate saucepan, add 1 tbsp of ground turmeric and cover with 2 cups of water. Bring a low simmer for 25-30 minutes. Strain and allow to come to room temperature. Add 1 tbsp of vinegar to the dye and mix.
Add enough of the dye liquid to submerge an egg to separate drinking glasses or ramekin dishes.
Submerge a white hardboiled egg in the yellow dye for at least 2 hours to make a vibrant yellow egg. Use a brown hardboiled egg for a darker yellow egg.
For the Green Easter Eggs
Submerge a white hardboiled egg in the blue dye for 2 hours.
Strain and transfer to the yellow dye for at least 30 minutes to make a light green egg.
Use the eggs as decor or you can easily still eat the eggs as hardboiled eggs as long as they stay refrigerated!
Notes
I highly recommend sticking with a majority of white eggs, because that will give you a blank canvas to add color to. You can also hard boil some brown eggs for darker colors.
Add more decor to the eggs by adding tape before dying them.
