The cadmium pigments eventually replaced compounds such as mercury(II) sulfide (the original vermilion) with greatly improved lightfastness. Cadmium pigments are known for excellent lightfastness, although the lighter shades can fade in sunlight. [6] A cadmium yellow paint was frequently used on Bob Ross' TV show The Joy of Painting.
Cadmium is also found in some industrial paints and may represent a hazard when sprayed. Operations involving removal of cadmium paints by scraping or blasting may pose a significant hazard. The primary use of cadmium is in the manufacturing of NiCd rechargeable batteries. The primary source for cadmium is as a byproduct of refining zinc metal. [1]

Cadmium red is a byproduct of zinc ore. About half of the cadmium produced in the world has been used for making batteries for automobiles, and a large part of the other half is used for making a family of bright pigments, including cadmium orange and cadmium yellow. It is known for maintaining its brightness.
For exposure to cadmium, which is toxic to the heart and many other organs, there is a low threshold (0.21-0.36 mcg per kilogram, or per 2.2 pounds, of body weight per day), according to the FDA.
Selenium, like manganese, can be used in small concentrations to decolorize glass, or in higher concentrations to impart a reddish color, caused by selenium nanoparticles dispersed in glass. It is a very important agent to make pink and red glass. When used together with cadmium sulfide, [9] it yields a brilliant red color known as "Selenium Ruby".
