A solid solution of cadmium sulfide (CdS) and cadmium selenide (CdSe), an inorganic pigment with the structure CdS・ nCdSe . As the content of cadmium selenide increases, the color changes from bright orange to scarlet or maroon. Some pigments contain barium sulfate as a strengthening agent. Specific gravity is 3.9-4.5, and it has good alkali resistance but not so good acid resistance. It has excellent heat resistance, but sublimes at 900-950°C. It has very good light resistance. This type has a wide range of colors and a well-balanced range of properties, making it versatile and used for coloring paints, printing inks, glass, ceramics, enamel, and plastics.
