Natural colorants do most of the heavy lifting in Panta Rei Made soaps. Powders, clays, botanicals, and plant materials behave differently from lab-made dyes, but they give each bar its subtle, real-world variation — the kind you only get in small batches. This guide walks through the most common types, what they do, and how they tend to behave in finished soap.


1. Botanical Powders

These include herbs, roots, flowers, and vegetal ingredients such as indigo, turmeric, alkanet root, spirulina, beetroot, hibiscus, and more.

What they do

  • Add natural, muted color (greens, purples, pinks, browns, yellows)
  • Provide visual texture — fine speckling, soft haze, or subtle marbling
  • Tie the color of the bar to an actual ingredient, not a synthetic pigment

How they behave

  • Color varies from batch to batch (normal for plant powders)
  • Some fade over time (e.g., beetroot, hibiscus)
  • Some deepen as the bar cures
  • Powders with larger particles add light exfoliation

2. Natural Clays

Clays offer some of the most predictable natural tones. Common options include kaolin, French green, rose/pink clay, Brazilian clays, rhassoul, and multani mitti.

What they do

  • Produce solid, stable colors that don't fade easily
  • Create a creamier, more stable lather
  • Add a softly matte appearance to the bar

How they behave

  • Clays can slightly thicken batter (important in layered soaps)
  • Lighter clays may shift subtly depending on scent oils

3. Spices

Spices like turmeric, paprika, cinnamon, annatto, and cocoa bring warm, saturated tones.

What they do

  • Turmeric = yellow to deep gold
  • Paprika = coral to reddish orange
  • Cocoa = tan to deep brown

How they behave

  • Some spices may add a light scent initially (it fades)
  • Paprika and turmeric disperse best when pre-mixed
  • Turmeric can slowly shift from bright yellow to warm amber

4. Botanicals & Florals as Toppers

Dried flowers, petals, seeds, and herbs don’t always color the soap itself, but they add texture and interest to the top or sides.

Common examples:

  • Chamomile
  • Cornflower
  • Calendula
  • Rose buds
  • Lavender buds

How they behave

  • Calendula holds color very well
  • Lavender buds may turn brown over time (totally normal)
  • Some botanicals soften slightly when exposed to steam during use

5. How Natural Colorants Influence Design

Because natural colorants are subtle and reactive, they shape the way a bar looks:

  • They encourage soft gradients instead of neon brightness
  • They create organic swirls, speckles, or marbled patterns
  • They make each bar slightly different — part of the charm

7. Why We Use Natural Colorants

A short explanation customers appreciate:

  • They support a cleaner formulation
  • They create authentic, non-uniform beauty
  • They are recognizable ingredients
  • They align with small-batch craft and transparency

This approach keeps each bar grounded in real materials — not synthetic dyes — while still delivering color that feels modern, clean, and intentional.
