About PO20
History
Cadmium orange (cadmium sulfoselenide) followed cadmium yellow in the late 19th to early 20th century.
In mixes
Opaque and strong, a warm orange that mixes cleanly with yellows and reds and covers well.
Genuine or hue?
Cadmium colors are opaque, warm and strong, but cost more and are toxic if swallowed or breathed in as dust. Hues are cheaper and safer, and usually more transparent, so they cover less well.
Drying speed is typical for linseed oil; tubes ground in safflower or poppy oil, or with driers added, will differ. These are general notes on the pigment, not on any one brand.
