Coloring Your Fizzy Bath Bombs

I know a bunch of you made delightful effervescent batches of Fizzy Bath Bombs last week. Usually, I'm satisfied leaving my Fizzy Bath Bombs just plain white with no colorant added. Perhaps you were too. If that's the case, you can skip this article, and just refer to the instructions in Make Fizzy Bath Bombs. But every once in a while...for a special occasion, or a holiday, or season, I'll add some color to them to make them a bit more special. Now you can too.
