I've been wanting to make some homemade bath salts, and while coloring them certainly isn't necessary, it would make them prettier, and since I'd like to use them for gifts...

All of the recipes I've seen call for food coloring as the coloring agent. Wouldn't that stain your skin or a fiberglass tub, or maybe even grout?

Any other ideas?
