There’s a colour that speaks in warmth, confidence, and passion - the colour of embers, ripe berries, and beating hearts. Heartfire captures that essence in fabric form: a natural red born from the earth itself.
At Wild Hue, every botanical powder dye is made from one plant only - no blends, no additives, no chemicals. Heartfire comes from the roots of Rubia tinctorum, better known as Madder Root - a plant revered for centuries for its deep, enduring reds.
This plant-based dye brings vibrancy without compromise. It’s colour you can feel - alive, earthy, bold - created through a process that honours both craft and sustainability.
Whether you’re working on clothing, home textiles, or DIY art, Heartfire infuses your creations with warmth, energy, and purpose.
Wild Hue’s botanical powder dyes bring the colour of plants directly to your fabric - pure, safe, and plant-based.
What Is Heartfire?
Let’s start with what makes this dye special.
This botanical powder dye is made from one single plant: Rubia tinctorum (Madder Root).
When the root is harvested, dried, and ground into fine botanical powder, it reveals pigments rich in alizarin and purpurin - compounds that yield shades ranging from coral red to crimson to burnt rust. The result is a natural red that feels ancient yet modern, vibrant yet grounded.
The beauty of Heartfire lies in its depth. Depending on the fibre and mordant, it can create soft pinks, fiery oranges, or deep brick reds. Every outcome is plant-driven and naturally unique - no two dye baths are ever quite the same.
For eco-conscious makers, this purity matters. A single-plant dye means transparency, biodegradability, and authenticity. You know exactly what’s in your colour - and more importantly, what isn’t.
That’s the Wild Hue promise: pure plant colour, nothing more.
History & Cultural Significance
Long before chemical dyes filled factories, the roots of Rubia tinctorum coloured the world in red.
Madder Root was one of humanity’s earliest dyes - traces have been found in ancient Egyptian linens and Roman textiles. Across Europe, Asia, and the Middle East, madder-dyed cloth symbolised vitality, courage, and connection to the land.
In medieval Europe, it was prized by weavers for its strong, lasting reds - used to colour soldiers’ uniforms and royal garments alike. In India and Persia, madder was cherished for block-printing and intricate pattern work. Wherever it travelled, it carried meaning: red as life, red as fire, red as art.
For centuries, artisans dyed with this one plant alone, just as Wild Hue continues today. Our Heartfire dye follows that lineage - the same humble root, reborn in modern, sustainable form.
To dye with Heartfire is to join a timeless conversation between soil, colour, and craft.
How to Use Heartfire at Home (DIY Tutorial)
You don’t need a studio to create with Heartfire. Here’s how to bring its warmth into your own textile projects.
You’ll Need:
-
Wild Hue Heartfire Botanical Powder Dye (100% Madder Root)
-
Fibre Bond (Wild Hue’s plant-friendly mordant)
-
Natural fabrics: cotton, linen, silk, wool, bamboo, or eucalyptus
-
Large pot or bucket, stirring stick, gloves
-
Mild detergent or vinegar for rinsing
Step-by-Step Guide:
-
Pre-wash your fabric.
Remove sizing, oil, or finish to help the dye absorb evenly.
-
Measure your dye.
50 g of Heartfire = ~1 kg fabric (medium tone)
100 g = ~2 kg fabric (deep tone)
-
Mordant your fibres.
For long-lasting results, treat your fabric with Fibre Bond before dyeing. It’s Wild Hue’s plant-friendly mordant that helps colours bind beautifully.
-
Prepare your dye bath.
Dissolve Heartfire powder in warm water (around 60–70 °C). Stir well to release the pigment from the root powder.
-
Add your fabric.
Submerge fully and stir gently for even coverage. Keep the bath warm, not boiling, to protect delicate fibres like silk and wool.
-
Let it steep.
Leave the fabric in the dye bath for 30–60 minutes, checking for colour depth. Longer immersion yields deeper reds.
-
Rinse and neutralise.
Rinse until the water runs clear, then dip briefly in a mild vinegar bath to help fix colour and remove excess pigment.
-
Dry naturally.
Hang in shade to preserve the richness of the colour.
Quick Dye Quantity Guide:
-
50 g = 1 kg fabric (soft rose to red-orange)
-
100 g = 2 kg fabric (deep red or rust tone)
-
Silk & wool: use lower temperatures
-
Cellulose fibres (cotton, linen, bamboo): absorb madder deeply and glow warmly
For longer-lasting results, use Fibre Bond, Wild Hue’s plant-friendly mordant, designed to help natural colours bind beautifully.
Science & Sustainability Notes
What gives Heartfire its glow?
The Science of Red
Madder Root contains a family of natural dye compounds called anthraquinones, including alizarin and purpurin. These are responsible for the rich range of red, orange, and pink hues that emerge during dyeing.
When heated in water, these pigments are released from the root and attach to fabric fibres with the help of a mordant - especially on cellulose fibres like cotton or linen. The result: long-lasting, vibrant reds that age gracefully.
Why One-Plant Dyes Matter
Unlike synthetic reds (which often rely on petroleum-derived chemicals and heavy-metal stabilisers), Heartfire is entirely plant-based and biodegradable. Using a single-plant botanical powder keeps the process transparent, safe, and circular.
Each batch of Heartfire returns to the soil harmlessly when washed out - no toxins, no residue, no guilt.
Sustainability at Its Core
-
100% biodegradable, renewable plant dye
-
Free from synthetic additives and toxins
-
Gentle on skin, fabrics, and waterways
-
Cruelty-free and vegan
-
Aligned with Wild Hue’s “One Plant Only” purity philosophy
When you use Heartfire, you’re colouring fabric with a pigment grown in the ground - not manufactured in a lab. That’s what makes every shade both beautiful and meaningful.
Modern Inspiration & Ideas
Red is a storyteller. It can be passionate, bold, or quietly earthy - depending on how you use it. Heartfire lends itself to countless creative expressions.

FAQ
Is Heartfire safe for sensitive skin?
Yes. Because it’s made purely from the Madder Root plant, Heartfire is naturally gentle and free from synthetic chemicals. Always rinse thoroughly before wearing.
Can I mix Heartfire with other Wild Hue dyes?
You can, though each Wild Hue colour is made from one plant only. For blended tones, try layering or overdyeing rather than mixing powders.
How long does the colour last?
With proper mordanting (using Fibre Bond) and gentle washing, Heartfire produces long-lasting, fade-resistant colour. It will soften slightly over time, giving your textiles an organic, lived-in beauty.
Do I need a mordant?
Yes. Using Fibre Bond helps the natural pigments bind to your fibres and ensures strong, lasting colour.
What fabrics absorb it best?
Cotton, linen, silk, wool, bamboo, and eucalyptus. Madder performs beautifully on cellulose fibres but also produces rich tones on protein fibres.
Is Heartfire vegan and cruelty-free?
Absolutely. Heartfire is 100% plant-based, ethically sourced, and cruelty-free.
Can I achieve lighter shades?
Yes. Simply use less dye or shorten immersion time to create blush pinks and soft terracotta tones.
