Yellow ochre, orpiment, Naples yellow, lead-tin yellow, Indian yellow, chrome yellow, and cadmium yellow – most toxic or at least harmful to someone.
von Dillis
Lead antimonate yellow was the original Naple Yellow, but had first been used long before in glassware. Paintings by Claude Lorrain, Böcklin, Renoir, and others.
It’s not Chinese, and for centuries was ignored, as lead white was preferred. It came into use during the 19th century, and is seen in paintings by Friedrich, Cézanne, van Gogh, Klimt, and Hodler.
