Indian yellow

A yellow coloring matter prepared from the evaporated urine of cows that have been fed on mango leaves. It is less fugitive than most other yellow lakes. In 1938, however, its production was prohibited on humane grounds, as mango leaves are harmful to the cattle. The term is also applied to a brilliant yellow pigment made from naphthol yellow and used in coating paper. (233 )
