Literary references to cadmium red predominantly emphasize its role as a distinctive, vivid pigment in the artist’s palette. Several texts note its definitive hue—often described as a deep, unmistakable orange-red—that captures immediate attention, whether in the depiction of drapery, skies, or as a standalone color choice [1]. Its introduction marked a turning point, replacing older, less reliable options and setting a new standard among permanent reds alongside other famous pigments such as madder reds and Mars red [2], [3]. Moreover, its technical designation in pigment charts—sometimes simply noted with a number or as “deep cadmium” [4], [5]—reinforces its established status and unique aesthetic contribution in artistic literature.
