(en-US)A bright greenish yellow pigment derived by reacting zinc oxide with potassium dichromate solutions, colors varying depending on the proportions of each component. It is toxic, stable to light, unaffected by hydrogen sulfide, having less covering power than chrome yellow. It is used in oil and watercolors alone and mixed with Prussian blue, strontium yellow, or barium yellow, as a rust inhibitor, and as a plastic colorant.
