Old Man's Beard (Usnea barbata Lichen) OrganicLichens were among the earliest dyes used in Europe, valued by the Anglo Saxons for embroideries and small wool embellishments. They belong to the remarkable group of dyestuffs that can create both warm oranges and the elusive purple shades, depending on the method and pH. Because they do not require mordants, lichen dyes are simple to use, though patience is key when working with the ammonia steeping method. Historical NoteLichens were sometimes used

Lichens were among the earliest dyes used in Europe, valued by the Anglo-Saxons for embroideries and small wool embellishments. They belong to the remarkable group of dyestuffs that can create both warm oranges and the elusive purple shades, depending on the method and pH. Because they do not require mordants, lichen dyes are simple to use, though patience is key when working with the ammonia steeping method.

Historical Note
Lichens were sometimes used as substitutes for Tyrian Purple, the mollusk-derived dye reserved for royalty and the elite. By fermenting lichens in ammonia (traditionally stale urine), dyers could create purples and violets that imitated this prized colour at a fraction of the cost. These processes were especially important in Northern Europe where mollusk purple was unavailable.

Active Coloring Compounds
Lichen acids such as orcein, lecanoric acid, and usnic acid (depending on species).
