Anotations

Scope note:

A yellow organic pigment composed of magnesium euxanthate, originally made from the urine of cows fed exclusively on mango leaves, producing a washed, powdered material that is a clear, golden yellow color. Used for watercolor and tempera paints. The production of Indian yellow was prohibited in 1908 because the mango leaves were harmful to the cattle. Current counterparts are made with a synthetic coal-tar derivative. Authentic Indian yellow fluoresces a bright yellow color when lit with long wavelength ultraviolet light.
