You can use Red Cabbage, onion skins (red or brown), beets, tea bags, paprika or coffee to dye eggs.

Add 1 quart of water and 2 tablespoons white vinegar to a large pan; if more water is necessary to cover the ingredients, proportionally increase the amount of vinegar. Bring to
a boil,then lower heat & allow the ingredients to simmer for 30 minutes. Strain dye into a bowl, and let cool.

Add eggs to the strained dye and boil 10 minutes, turn off the heat and let the eggs sit for another 10 minutes. Take out and cool on paper towels, refrigerate.
