No single value: Woad is a material, and its colour varies. The background shows its family, blue.

Grown across Europe since ancient times, it was the main source of blue for textiles and art before indigo and synthetic dyes took over.

What colour is Woad?
Woad is a flowering plant in the mustard family, known for the blue dye made from its leaves. The colour it produces ranges from grey-blue to deep midnight blue, depending on how it is processed. Woad blue is darker than many modern blues and was prized for its lasting quality on textiles and in art. The plant itself has yellow flowers and was once a common sight in European fields.
Where does Woad come from?
The name 'woad' comes from its use as a dye and a medicinal plant. 'Isatis' refers to its ancient role in treating wounds, while 'tinctoria' points to its dyeing properties. Woad has been used since the Neolithic period, with seeds found in ancient France and Germany. It became central to European dyeing from ancient times through the Middle Ages, especially before indigo arrived from Asia.
How is Woad made?
The blue dye is extracted from the leaves of the woad plant. Leaves are harvested, crushed, and fermented to release the dye chemical, indigo, though in lower concentration than in true indigo plants. The resulting paste or powder is then used to dye textiles or make pigment for paint. The process is environmentally safe, and woad is biodegradable.
Where Woad is used
Woad was once the main blue dye for textiles in Europe, used in cloth, tapestries, and even illuminated manuscripts. Regions like Languedoc in France and Lincolnshire in England grew rich from its trade. It was also used in art, such as the Lindisfarne Gospels, and in traditional fabric printing in Germany. Today, it is still used by craft dyers and for some inks.

Woad dye produces a blue similar to indigo, but usually darker and less intense. It can range from grey-blue to nearly black, depending on the binder and method. Woad is sometimes confused with indigo, but the two come from different plants and woad contains less of the dye chemical. The term 'pastel' in southern France refers to woad blue.
