Heritage
Yellow ochre is, with red ochre, one of the two pigments humans have used continuously for the longest time. Indian Yellow — historically made from the urine of cows fed only mango leaves — reached its peak in 17th–18th century Mughal painting before falling out of use. Cadmium yellow, introduced in the 1840s, gave Van Gogh his sunflowers; chrome yellow gave him the wheat fields he died in. Modern PY83 (a hansa yellow) is the durable workhorse of contemporary printing.
