Viridian is a blue-green pigment, a hydrated chromium(III) oxide, of medium saturation and relatively dark in value. It is composed of a majority of green, followed by blue. The first recorded use of viridian as a color name in English was in the 1860s.[1] Viridian takes its name from the Latin viridis, meaning "green".[1]: 18–19 The pigment was first prepared in mid-19th-century Paris and remains available from several US manufacturers as prepared artists' colors in all media.[2]: 276–77
History
[edit]Viridian pigment was first prepared in 1838 in Paris by Parisian color chemist and painter Pannetier alongside his assistant Binet as a hydrated form of chromium oxide.[3][4] The preparation process was demanding, expensive, and shrouded in secrecy.[2]: 275 The French chemist C. E. Guignet developed and patented a cheaper manufacturing method in 1859 that enabled larger distribution and use of the pigment.[2]: 274 This method involved calcining a combination of boric acid and potassium bichromate, then washing the material.[2]: 280–281
Winsor and Newton's catalogue listed the pigment as early as 1849. It was used as early as 1840 in a work by J. M. W. Turner.[2]: 275 Viridian was in prominent use by the mid-nineteenth century, but was less popular than three to four times more affordable alternatives including emerald and chrome greens.[2]: 276–77

Permanence
[edit]Viridian is considered durable and permanent as an artist's pigment. Viridian is unaffected by temperatures up to 260 °C (500 °F), but it is unsuitable for use in ceramic glazes. Viridian is compatible with all pigments in all media, and has high oil absorption. Pure pigment formulations of viridian are hard and may separate in tubes, but adding barium sulfate in small quantities enables easy grinding and dispersion.[2]: 278
