Lincoln green is the colour of dyed woollen cloth associated with Robin Hood and his merry men in Sherwood Forest, Nottinghamshire. The dyers of Lincoln, a cloth town in the high Middle Ages, produced the cloth by dyeing it with woad (Isatis tinctoria) to give it a strong blue, then overdyeing it yellow with weld (Reseda luteola) or dyers' broom, Genista tinctoria. "Coventry blue" and "Kendal green" were also colours linked with the dyers of English towns.
The first recorded use of Lincoln green as a colour name in English was in 1510. By the late sixteenth century, Lincoln green was a thing of the past. Michael Drayton provided a sidenote in his Poly-Olbion (published 1612): "Lincoln anciently dyed the best green in England." Cloth of Lincoln green was more pleasing than undyed shepherd's gray cloth: "When they were clothed in Lyncolne grene they kest away their gray", according to A Lytell Geste of Robyn Hode, ca 1510, and Lincoln green betokened an old-fashioned forester even in the fancy dress of Edmund Spenser's The Faery Queene:
"All in a woodman's jacket he was clad
of Lincolne Greene, belay'd with silver lace."
Robin Hood's Garland, the popular ballad printed in eighteenth-century compilations, offers an unexpected picture of Robin as he presented himself at court:
He cloathed his men in Lincoln green
And himself in scarlet red"
The distinction was in the cost of scarlet, which was dyed with kermes, derived from the Kermes vermilio insect native to the Mediterranean. Lincoln scarlet, from its imported dyestuff, was more expensive than Lincoln green. In 1198 the Sheriff of Lincoln bought ninety ells (about 112 yards) of scarlet cloth for £30 (6s 8d per ell); although the cloth was a finely finished fabric, its high price was almost certainly due mainly to the extremely costly dye-stuff, greyne (graine) from Kermes or scarlet grain. In 1182 the Sheriff of Lincoln bought Scarlet at 6s 8d/ell, Green and Blanchet both at 3s/ell and Gray at approximately 1s 8d/ell. By 1216 three guilds controlling the cloth trade were established in Lincoln, the Weavers', Dyers', and Fullers' guilds.
"Lincoln-green" was revived in the years prior to the Great War (World War I), when it was adopted as the colour of the full-dress uniform of the Lincolnshire Yeomanry. This military version took the form of a distinctively light shade, which contrasted sharply with the sombre rifle green widely worn by other regiments of the British Army.
In popular culture
Sir Walter Scott in his 1820 novel Ivanhoe mentioned Lincoln green three times - Chapters VII: "“One of these, a stout well-set yeoman, arrayed in Lincoln green, having twelve arrows stuck in his belt,”  Also in Chapters XV and XXXIII.
William Makepeace Thackeray in his 1848 novel Vanity Fair mentioned Lincoln green—Chapter III: "What causes them to labour at piano-forte sonatas, and to learn four songs from a fashionable master at a guinea a lesson, and to play the harp if they have handsome arms and neat elbows, and to wear Lincoln Green toxopholite hats and feathers, but that they may bring down some "desirable" young man with those killing bows and arrows of theirs?"
