Chrome Yellow is a natural yellow pigment made of lead(II) chromate (PbCrO4). It was first extracted from the mineral crocoite by the French chemist Louis Vauquelin in 1797. Because the pigment tends to oxidize and darken on exposure to air over time, and it contains lead, a toxic, heavy metal, it has been largely replaced by another pigment, Cadmium Yellow (mixed with enough Cadmium Orange to produce a color equivalent to chrome yellow). Cadmium pigments on their own are toxic as well from the cadmium content, and have themselves been replaced with azo pigments. This pigment has bright color, with strong tinting strength, high hiding power, good light fastness and dispersibility.
