Mars Black is a widely used pigment with a high rating for opacity, lightfastness and permanence. It is also non-toxic and has no known health hazards. Matisse Mars Black is completely opaque with a warm, brownish undertone. It is made from inorganic synthetic iron oxide, and is a fairly recent invention from the early 20th century.
However, in a relatively short time this paint has become a staple colour recommended for beginners and advanced acrylic painters. Mars Black also has extremely strong tinting strength, approximately three times that of Ivory Black and should be added to other colours with caution until its influence is understood.
