Natural Dye - Black Walnut Powder

Dark Walnut Powder is a rich, natural dye made from the hulls of the black walnut tree (Juglans nigra). It yields deep browns, warm taupes, and charcoal-tinged neutrals without requiring a mordant. Highly concentrated and naturally colourfast, it’s a go-to dye for achieving depth and elegance in natural textiles.

Benefits
Dark Walnut is renowned for its strength, simplicity, and natural sophistication. It gives textiles a grounded, earthy tone that pairs beautifully with natural fibres and complements softer hues. Perfect for creating antique or weathered finishes.
