Färberwaid
Lincoln green is the colour of dyed woollen cloth formerly originating in Lincoln, England, a major cloth town during the high Middle Ages. The dyers of Lincoln, known for colouring wool with woad ("Isatis tinctoria") to give it a strong blue shade, created the eponymous "Lincoln green" by overdyeing this blue wool with yellow weld ("Reseda luteola") or dyers' broom, "Genista tinctoria". Other colours like "Coventry blue" and "Kendal green" were linked to the dyers of different English towns.
