Natural Colorants - Blue, Purple and Gray

Many soapers and crafters got into their craft because they wanted to make and use the most natural products possible, and to be able to control what ingredients are in the products they use. One way to do that is to use herbs and other natural colorants in products. They can be a bit unpredictable, but are also fun to use and can yield some very beautiful results.

Here are some natural colorants to use that will yield blue, purple and grey tones in your product:

Alkanet root (dried, infused in oil) – maroon to indigo. Begins mauve/lavender, turns pinkish. Very pH sensitive.

Beet root (dried) – soft pink to red to purple, depending on amount used

Bentonite (clay) – beige to green to grey

Blackberries (dried or pureed) – purple to blue

Blue Chamomile essential oil – robin’s egg blue to light green

Glacial clays – grey to brown

Hibiscus, red (dried or powdered) – purple

Indigo root (infused in oil) – deep blues. Caution – can stain

Mulberries, black (pureed or dried) – red violet to dark bluish purple

Myrtle berries (pureed or dried) – maroon to purple

Oregon grape berries (pureed or dried) – purple

Pumice, ground – grey. Adds abrasiveness to scrubs, gardener’s soaps, kitchen soaps, etc.

Spirulina/blue-green algae – bluish green

Woad leaves (dried, infused in oil) – blue
