Hi Holly! I'm sorry this color wasn't your favorite. In our tests and recipes, we've found it creates a nice pastel blue color. As seen in this LaBomb Colorants blog post, we used about 9 drops in 8-10 oz of bath bomb mix to get a blue color. Also, these colorants are listed under Colorants, LabColors, Bath Bomb Dyes. You can also find them here. I'll be emailing you personally to discuss this!
