# Best Natural Soap Colorants From Clays and Botanicals Source: https://soapmakingnest.com/best/best-natural-soap-colorants Updated: 2026-10-02 Publisher: Soap Making Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://soapmakingnest.com/how-we-research#our-score Natural soap colorants are plant, clay, and mineral powders, think French clays, spirulina, madder root, annatto, and activated charcoal, that tint soap without synthetic dyes. Home soap makers choose them for earthy, muted palettes and for a fully natural ingredient label that customers increasingly ask for. Results are more subtle and variable than synthetic color, so look for colorants known to stay stable in cold process, since some botanicals brown or fade in high-pH batter. Check the recommended usage rate, as too much clay can drag or crack a bar, and confirm the powder is finely milled to avoid speckling. Testing a small batch first shows how each colorant reads at trace and after the cure, since natural tones often shift as soap saponifies and ages. ## Picks ### 1.
