Chrome orange [1344-38-3], C. I. Pigment Orange 21:77601, is a basic lead chromate with the composition PbCrO4 — PbO but is no longer of technical or economic impor­tance. This product was obtained by precipitating lead salts with alkali chromates in the alkaline pH range. By controlling pH and temperature, the particle size and thus the hue could be varied between orange and red.
