Green earth, also known as terre verte and Verona green, is an inorganic pigment derived from the minerals celadonite and glauconite.[1][2][3] Its chemical formula is K[(Al,FeIII),(FeII,Mg](AlSi3,Si4)O10(OH)2.[4]

First used by the ancient Romans, green earth has been identified on wall paintings at Pompeii and Dura-Europos.[5][6] The Renaissance painter and writer Cennino Cennini claimed that “the ancients never gilded except with this green” being used as a bole, or undercoating. In the Middle Ages one of its best-known uses was in the underpainting of flesh tones.[4]

High quality deposits can be found in England, France, Cyprus, Germany and at Monte Baldo near Verona in Italy.[6] The color ranges from neutral yellow green to pale greenish gray to dark matte olive green.[4][3]
