Chrome orange

Chrome orange: Chrome orange, also known as chrome red, is an orange pigment 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.
