Albrecht Dürer (1471-1528) was a great German Renaissance artist that was famous for his portraits and engravings. His palette did not change much throughout his painting career and included the best pigments available at that time.
This watercolor palette includes all the pigments used by Dürer includes original pigments with two substitutes and one additional pigment. The substitutes are Viridian and Rose Madder. They replace Verdigris and Cochineal - similar colors that are extremely fugitive. Additional pigment is Ultramarine, a modern version of rare and expensive Azurite. Dürer made efforts to obtain good quality Azurite, mostly for his religious artworks, and paid large sums of money for it. Since the available Azurite looks less blue and saturated than the one on Dürer's paintings, adding modern pigment seemed like a good addition to help represent the true color palette.
There are two versions of Dürer's palette: original pigments and non-toxic substitutes.
