We did a little kitchen experimenting and cooked up some natural egg dyes. We used supplies we had on hand – beets, turmeric, yellow onion skins, and frozen blackberries.
I'm really impressed with the rich orange and yellow, but I was hoping for a brighter result from the beets. Those things stain my hands in an instant – why not eggs? The berries gave us a dingy gray. Blah. But overall, a fun little experiment.
A google search for natural egg dyes will get you tons of recipes, but I found the best variety on this site.
