A dull, olive-green colour pigment. Anhydrous, opaque chrome oxide green was first made in 1809 by Vauquelin and was listed as an artists pigment in the 1840 Winsor and Newton catalogue (Newman 1997). It is opaque, lightfast, and durable with excellent resistance to chemicals and heat. Chromic oxide has limited use in paints because of its dull colour. Chromium oxide is also used as an abrasive.
