Cadmium pigments were discovered in 1817 by German chemist Friedrich Stromeyer. By the 1840s, cadmium yellow and red became available to artists. The Impressionists and Fauvists embraced cadmium colours for their unmatched brilliance and opacity. Today, cadmium pigments are being phased out in some countries due to environmental regulations.

Pure, aggressive, and uncompromising. Cadmium red demands attention without apology. It is the red of stop signs, fire engines, and alarm — pure visual energy. In large fields, it can feel overwhelming; in small accents, electrifying.

Became the defining red of Modernism. Matisse and his Fauvist circle used cadmium red to break from naturalistic colour. Today it remains the benchmark for red pigment quality, though environmental concerns are pushing artists toward cadmium-free alternatives.
