A pale yellow pigment that is also called strontium yellow. Strontium yellow was used in oil paints in the late 19th and early 20th centuries. It has good opacity and stability to light and heat. But because of its high hiding power, strontium chromate was not used in watercolors. Commercially strontium chromate was often mixed with other pigments; a mixture with blue Prussian blue was sold as green cinnabar and a mixture with yellowH barium yellow and yellow zinc yellow was sold under the name lemon yellow or citron yellow. Currently strontium yellow is used in anticorrosive coating and pyrotechnics.
