Adding color is one of my favorite parts of the soapmaking process. Color in soap can convey different places, scents, themes or moods. If you prefer to keep your soap as natural as possible, there are a wide variety of colorant options. Various clays, herbs, botanicals and powders can give soap surprisingly vibrant hues. If you’d like to browse natural colorant options, click here for clays and here for herbs and botanicals.
To demonstrate various natural colorants in cold process soap, I uploaded this photo onto Instagram. I was so blown away by the response (!). Because of that excitement level on Instagram, I decided to do a more in-depth post about the process and usage rates. Check out the natural colorant tests below. Aren’t they gorgeous? In particular I adore the way that rose clay, purple Brazilian clay and green zeolite clay look in cold process soap. I love working with natural colorants and ingredients in cold process soap so much, I wrote a whole book about it! My new book, Pure Soap Making, is available for pre-order now and only uses natural and nature-identical colorants (like pigments and oxides).
