Color Index
The pigments used are both inorganic and organic. The inorganic pigments have been used since antiquity and the vast majority come from or are extracted from minerals and clays, such as natural earths, siennas, and ochres. Titanium pigments, carbon black, ultramarine blue, cobalts and cadmiums also belong to this category. Many of them are currently synthesised in industrial processes. Organic pigments are more modern, developed at the beginning of the 20th century thanks to new synthesis methods in Organic Chemistry. These synthetic pigments are now a very important group in the manufacture of colours for artists, producing bright and luminous shades with extraordinary intensity and excellent stability and permanence. The range of organic pigments is currently very extensive and includes azo pigments, blues, phthalocyanine greens, dioxazines, pyrroles, anthraquinones, quinacridones, etc.
