Black Spinel: This most permanent of blacks is the only truly neutral black in masstone and tint. Because of its pigment’s crystalline shape, Black Spinel dries to a matte finish when no painting mediums are added. Long and ropey in texture, it contains no carbon. Costs as much as Cadmium Yellows – but well worth the money.
Pigment: Copper chromite black spinel (PBk 28)
Vehicle: Alkali refined linseed oil
