Color Me Crunchy: Natural Ways to Color Handmade Soap (No Dyes, No Drama)
If you’ve ever peeked at a bar of soap and thought, “Wow, I want that in my shower and my soul,” then you, my dear, are ready to paint with nature. Coloring handmade soap naturally isn’t just gorgeous – it’s old-world earthy, kid-safe, toxin-free, and full of herbal goodness.
Here’s your guide to going full-on crunchy goddess with your soapcraft.
1. Clays for Earthy Elegance
- Rose Clay (Pink Kaolin): Soft pinks to dusty rose – great for gentle exfoliation and drawing out toxins.
- French Green Clay: Gives a cool sage or minty green vibe. Detoxifying and fab for oily skin.
- Bentonite Clay: Light gray to pale green – calming and creamy in the lather.
Bonus: Clays add slip to your soap, making it perfect for shaving bars.
2. Botanical Powders (aka Soap Color Fairy Dust)
- Spirulina: A vibrant green from blue-green algae. Use lightly – it can fade over time.
- Moringa Powder: Earthy green, rich in antioxidants.
- Turmeric: Bold yellow-orange. Start small – it stains (but in a fun sunshine way).
- Annatto Seed Powder or Infused Oil: Orange to deep gold (you know her, you love her).
- Beetroot Powder: Pinkish hue in melt & pour, but fades in cold process (best as swirl or top dust).
- Alkanet Root Powder or Infusion: Stunning lavender to deep purple. The crunchy goth’s dream.
3. Infused Oils (Slow and So Worth It)
Infuse herbs or colorants into your oils before soapmaking for a deep, consistent hue. Just place your herb/spice in oil and let it steep (2 weeks or gentle heat infusion).
- Calendula Petals in Olive Oil: Golden yellow
- Paprika in Sunflower Oil: Coral orange
- Chlorophyll Oil: Gorgeous grassy green
Pro Tip: Strain well to avoid specks unless you want that rustic, botanical look.
4. Charcoal and Cocoa, Baby
- Activated Charcoal: Deep black or gray. Great detox bar. Use sparingly!
- Cocoa Powder: Soft brown – smells divine if you add a hint of vanilla EO.
5. Juices and Purees (Use With Caution)
Some natural colorants come from food-grade fun, but watch for spoilage:
- Carrot Juice or Puree: Soft orange and vitamin-rich.
- Spinach Juice: Light green (can fade).
- Pumpkin Puree: Soft peachy gold.
Freeze these into cubes and use as your water replacement in cold process soap to keep the lye happy.
Things That Might Fade (But Are Still Pretty for a While)
- Beetroot
- Red cabbage juice (can go blue!)
- Hibiscus tea (starts pink, often turns brownish)
- Blueberries (don’t trust them, they lie)
Still worth experimenting with if you're doing a melt & pour project or don’t mind a little color drama.
Quick Crunchy Tips for Natural Soap Coloring:
- Test in small batches – natural colors can morph in lye like a mischievous faerie.
- Always use gloves – turmeric and annatto are out for blood (aka permanent stains).
- Label your bars! Some natural colorants carry skincare benefits too.
- Store your soaps away from sunlight to prevent fading. Sunlight is rude to delicate botanicals.
- Use powdered herbs or teas for gentle exfoliation AND color. Double win.

Your tools? A little patience, a lot of love, and a kitchen that smells like nature herself just brewed a potion.
