Historical synthetic single monopigment pigment sap green. It's also known as nitrous green, it is one of the first iron chelates based pigments developed in the early 1900s. Nowdays PG8 is practically out of production pigment and it''s rarely used in fine arts, 

 We have chosen this old green for its purity and almost submarine hypnotic depth, unique among historical greens.
