Viridian is a blue-greenpigment, a hydratedchromium(III) oxide, of medium saturation and relatively dark in value. It is composed of a majority ofgreen, followed byblue. The first recorded use ofviridian as a color name in English was in the 1860s.[2] Viridian takes its name from theLatinviridis, meaning "green".[3] The pigment was first prepared in mid-19th-century Paris and remains available from several US manufacturers as prepared artists' colors in all media.[4]: 276–77
Viridian pigment was first prepared in 1838 in Paris by Parisian color chemist and painter Pannetier alongside his assistant Binet as a hydrated form ofchromium oxide.[5][6] The preparation process was demanding, expensive, and shrouded in secrecy.[4]: 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.[4]: 274 This method involved calcining a combination ofboric acid andpotassium bichromate, then washing the material.[4]: 280–281
Winsor and Newton's catalogue listed the pigment as early as 1849. It was used as early as 1840 in a work byJ. M. W. Turner.[4]: 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.[4]: 276–77
Viridian is a bright shade ofspring green, which places the color between green andteal on thecolor wheel, or, in paint, atertiary blue–green color. Viridian is dark in value, has medium saturation, and is transparent.[4]: 275
