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 )
