Chrome orange

Chrome orange, also known as chrome red, is a range of orange pigments which consists of lead(II) chromate and lead(II) oxide. (PbCrO4 and PbO). Chrome orange can be made by precipitating lead(II) together with chromate in a basic solution or by treating chrome yellow with lye. It is toxic both from the contained lead and from the contained hexavalent chromium.

It was used in the past as a pigment in paints, but is now restricted or illegal because of the drive to reduce or remove lead and its compounds from paints.

Chrome orange was used extensively in Frederic Leighton's Flaming June (1895; Museo de Arte de Ponce).[1]
