Natural Dye - Logwood Powder

Logwood Extract produces rich purples, smoky greys and deep near-black tones, making it one of the most versatile dark shades in the natural dyer’s palette. Derived from the heartwood of Haematoxylum campechianum, this historic dye has been used for centuries and continues to be valued for the depth and complexity of colour it can achieve.

In extract form, logwood offers the convenience of a concentrated powder that dissolves easily in water. Only small amounts are needed to produce strong, saturated colour, allowing dyers to achieve consistent and reliable results while maintaining the distinctive character of natural dyes.

Depending on the mordant and fibre used, Logwood Extract can produce a wide tonal range, from soft charcoal greys through to rich violet and purple shades. This versatility makes it particularly popular for projects that call for deeper, more dramatic colours.
