Cadmium pigments are a class of pigments that have cadmium as one of the chemical components. Most of cadmium produced worldwide has been used in the production of rechargeable nickel-cadmium batteries — themselves being replaced by other rechargeable nickel-chemistry cell varieties like NiMH cells — but about half the remaining consumption of cadmium, which is about 2,000 tons annually, is used to produce colored cadmium pigments. The principal pigments are a family of yellow/orange/red cadmium sulfides and sulfoselenides as well as compounds with metals other than cadmium.
Brilliantly colored, with good permanence and tinting power, cadmium yellow, cadmium orange and cadmium red are familiar artists’ colors, as well as being frequently employed as architectural paints, since they can add life and vibrancy to renderings. Their greatest use is in the coloring of plastics and specialty paints which must resist processing or service temperatures up to 3,000 °C (5,430 °F). The color-fastness or permanence of cadmium requires protection from a tendency to slowly form carbonate salts with exposure to air. Most paint vehicles accomplish this, but cadmium colors will fade in fresco or mural painting.
The following are commonly used as pigments in artists' paints:
When first introduced, there were hardly any stable pigments in the yellow to red range, with orange and bright red being very troublesome. The cadmium pigments eventually replaced compounds such as mercury sulfide (the original vermilion) with greatly improved light-fastness.
Cadmium pigments are known for excellent light-fastness, although the lighter shades can fade in sunlight. A cadmium yellow paint was frequently used on Bob Ross' TV show, The Joy of Painting.
