Art Spectrum® Raw Sienna Soft Round Pastel shades.
Based on a form of natural clay pigment used since prehistoric times.
Art Spectrum® Raw Sienna is enriched with Mars Yellow to bring out its earthy warmth. Sienna is one of the most ancient pigments used by humans, and it was particularly popular during the Renaissance for use in underpainting and drawing, especially in its heated form, Burnt Sienna. The colour takes its name from the Italian city of Siena where the pigment was mined until the 1940s.
Today it is mainly sourced from the Italian Islands of Sardinia and Sicily and the Appalachian mountains in North America. These deposits are incredibly old, dating as far back as 4.6 billion years old. Indeed, the youngest deposits are over 540 million years old!.
