Slice the eggs in half from top to bottom. Scoop the yolks into a medium mixing bowl and lay the whites on a serving platter. Sprinkle the whites with salt.
Place all of the dry peppercorns, except 1/2 teaspoon of the pink peppercorns, into a spice grinder and process until ground well. Add the ground peppers, chopped green peppercorns and their brine, mayonnaise and mustard to the egg yolks and using a fork, stir to thoroughly combine.
Place the mixture into a zip top-plastic bag and cut a small hole at one of the corners. Pipe the mixture into each of the white halves. Coarsely grind the remaining 1/2 teaspoon of pink peppercorns and use to garnish the top of each egg.
