The story of PY35
The standard for opacity and lightfastness in yellow - vivid and permanent, though it requires care because of its cadmium content.
How it is made
Cadmium yellow is precipitated from cadmium salts and calcined to the desired shade, from pale lemon to deep. Ground in oil it gives a dense, opaque, brilliantly lightfast yellow.
In the hands of the masters
A mid-19th-century arrival, cadmium yellow gave Monet, Cézanne and the Post-Impressionists a permanent, brilliant yellow the Old Masters never had.
