The inorganic ones have been used since antiquity and the great majority come from or are extracted from minerals and clays, such as natural earths, siennas, and ochres. Titanium, carbon, ultramarine blue, cobalts and cadmiums pigments 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 the 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 tones 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.","brand":"Vallejo Colors","offers":[{"title":"Default Title","offer_id":64141512769866,"sku":"22930","price":0.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/0963\/2330\/files\/vallejo-studio-acrylic-200ml-930.jpg?v=1793260653","url":"https:\/\/vallejocolors.com\/en\/products\/amarillo-fluorescente-4","provider":"Vallejo Colors","version":"1.0","type":"link"}
