Kadmiumgelb

Kadmiumgelb, or cadmium yellow, is a family of bright, inorganic pigments based on cadmium compounds, most commonly cadmium sulfide (CdS). The standard form is CdS, while some variants are doped with selenium to give yellows ranging from pale lemon to deeper golden tones. Commercial lines distinguish cadmium yellow light, medium, and deep, reflecting different dopants and particle formulations.

These pigments are valued for their high opacity, strong tinting strength, and excellent lightfastness, making them a staple in professional artists’ paints as well as in ceramics, glass, and certain plastic colorants. The color range covers vivid, clean yellows that remain relatively stable under prolonged exposure to light, though hues can shift slightly with mixing and formulation. They are typically more opaque than many organic yellows, contributing to bright, covering applications.

History and usage: Cadmium yellow was developed in the early 20th century and became widely used through the mid- to late 20th century. Today it remains popular in many paint lines for its brightness and durability, although some manufacturers have reduced or restricted cadmium content in consumer products due to safety and environmental concerns.

Safety and regulation: Cadmium compounds are toxic if ingested or inhaled, and exposure considerations drive strict handling guidelines and regulatory controls in many regions. Artists and manufacturers follow safety practices, including proper ventilation and protective equipment, and disposal is subject to environmental regulations. Because of health and environmental concerns, there is ongoing interest in non-cadmium alternatives for yellow pigments.

Applications: Beyond fine art paints, cadmium yellow is used in ceramic glazes, glass coloration, and certain plastics where its brightness and stability are advantageous.
