M. Graham Artists’ Watercolor Tubes are made with thoughtfully selected pigments and Northwest blackberry honey, a nod to early artists who sourced their materials from nature. Custom-milled to preserve the unique qualities of each pigment, the honey’s viscosity enhances color strength and ensures easy dilution, yielding fluid, uniform washes. It also prevents colors from hardening on the palette and in the tube.

Properties
Cadmium Red is a bright, warm red that ranges in shade from orange-red to maroon and is available in light, medium, and dark versions. It is strong and opaque, with good tinting strength. Cadmium Red dries slowly. It grays down when mixed with white, mixes well with blues to create a range of browns, and mixes well with Cadmium Yellow to create a strong orange. It also works well in neutral mixes. Cadmium pigments have been partially replaced by azo pigments, which are similar in lightfastness to the cadmium colors, cheaper, and non-toxic. Hues vary by brand. Cadmium Red is usually available in either a pure grade or a cadmium-barium mix. The cadmium-barium mix has the same permanence as pure Cadmium Red, but it has a lower tinting strength.
Permanence
Cadmium Red is lightfast and permanent in most forms, but like many cadmium pigments, it will fade in fresco or mural painting. Its improved lightfastness has helped it to replace Vermilion on the artist’s palette.
Toxicity
Cadmium Red is a known human carcinogen. It is extremely toxic if inhaled and slightly toxic if ingested.
History
Cadmiums get their names from the Latin word cadmia meaning zinc ore calamine, and the Greek word kadmeia, meaning Cadmean earth, first found near Thebes, the city founded by the Phoenician prince Cadmus. Metallic cadmium was discovered in 1817 by Friedrich Strohmeyer, but Cadmium Red was not introduced until 1907 in Germany.
Description
Cadmium Scarlet, Selenium Red.
