Verdigris (copper acetate) gave medieval manuscripts many of their greens; it was unstable, eating through parchment over centuries. Terre verte (green earth) was used for under-painting flesh in the Italian tradition.

Modern green pigments are remarkably stable.
Green is closely associated with Islam — it appears on the flags of many Muslim-majority nations and on the Green Dome in Medina. In Ireland green is national identity, partly through the shamrock and partly through the political binary with orange.

Starbucks moved its logo from the original 1971 brown to green in 1987. John Deere's green and yellow has marked its machines for more than a century. U.S. banknotes have been printed in green since the 1860s; the Bureau of Engraving and Printing says no one can say for certain why green was first chosen, but it kept the color for the 1929 small-size notes because the pigment was plentiful, durable, and associated with the government's stable credit.
