Cook eggs to a hard boil consistency then peel. I did mine in the instant pot for 9 minutes. Stovetop is also fine.
Take 3 roughly 1-litre/2-pint jars and put 4 eggs in each then set aside.
For the yellow eggs
In a small saucepan bring 1 cup of apple cider vinegar, 1 cup of water, 2 teaspoons of salt, and 2 teaspoons of sugar to a boil.
Add in the turmeric and peppercorns and mix well to combine.
Remove from the heat and allow to cool for 5 - 10 mins, then pour over the eggs in one of the jars. Give the jar a swirl to make sure all the eggs are well coated, place a lid on it and put it in the fridge overnight.
For the pink eggs
In a small saucepan bring 1 cup of apple cider vinegar, 1 cup of water, 2 teaspoons of salt, and 2 teaspoons of sugar to a boil.
Add in the chopped beetroot, shallots, and bay leaf. Bring back to the boil then remove from the heat.
Allow to cool for 5 - 10 mins, then pour over the eggs in the second jar. Give the jar a swirl to make sure all the eggs are well coated, place a lid on it and put it in the fridge overnight.
For the purple eggs
In a small saucepan bring 1 cup of apple cider vinegar, 1 cup of water, 2 teaspoons of salt, and 2 teaspoons of sugar to a boil.
Add in the chopped red cabbage and caraway seeds. Bring back to the boil then remove from the heat.
Allow to cool for 5 - 10 mins, then pour over the eggs in the third jar. Add in ½ a teaspoon of baking soda, let the fizz settle, then add in the other ½. Once the fizz has completely settled, give the jar a swirl to make sure all the eggs are well coated, place a lid on it and put it in the fridge overnight.

Notes
Store pickled eggs in their pickling liquid in an airtight container - such as a jar, in the fridge. These are best enjoyed within a week of being made for optimal flavour and texture. Always ensure the eggs remain covered by the liquid, use clean utensils for removal from the jar, and avoid reusing the brine to make a new batch.
