Art Spectrum® Spectrum Viridian is a deep semi-transparent emerald green that is on the cooler side of the spectrum. Slightly muted, Viridian has often been a staple for landscape painters. The name originates from the Latin word for green ‘viridis’. Viridian was first made in 1838 in Paris by the colourist Binet as a replacement for the dangerous Emerald Green.
