Seldom used at full tube strength, this transparent, non-staining
pigment is an excellent glazing pigment and a portrait painter’s
essential. It’s a cool blue-green useful in mixing without staining
other pigment particles and for soft edges in florals. It is the secret
hidden ingredient in Moonglow. Viridian can quickly modify reds, and in
combination with the Quinacridones, its versatility has multiplied.
