The idea of colored bubbles has never come across my mind. Really. Even with this in-depth imagination I have. I found about about these miraculous suds... through Jackie of Sweetie Pie Pumpkin Noodle. They are non-toxic, non-staining, and so unbelievably vivid. Boy, do they have hefty price on them... 15 bucks for two - 4 oz. bottles.
