Cadmium red comes for Matisse
The Red Studio, Henri Matisse — Museum of Modern Art, New York
Matisse was much taken with this strong new red, which has excellent stability. He recounts that he attempted, unsuccessfully, to persuade Renoir to adopt a “cadmium red” in place of the traditional cinnabar. Matisse inherited the use of intense cadmium red, a 19th century invention, from the Impressionists. The critic John Rusell called this canvas "a crucial moment in the history of painting. Color is on top, and making the most of it."
