I'm a newbie maker and I'm struggling to find a good colorant that is not only vibrant but also cost-effective. You know those Lush bath bombs that have a really really vibrant color and great smell and do not stain the tub? I want something like that. Labomb colorants have a lot of good rep but the color looks really pastel (I know I can add more of it to make it darker, but it's really expensive on Brambleberry). Wilton icing dyes are really pigmented but it's not FDA approved for cosmetic purposes and I consider giving my bath bombs as gifts.
Also any oils you guys suggest to mix in? How does witch hazel help?
