Inorganic pigments have been used since ancient times and most are derived from or extracted from minerals and clays, such as natural earths, siennas and ochres. Titanium, carbon, ultramarine blue, cobalt and cadmium pigments also belong to this category. Many of these are now synthesised through industrial processes. Organic pigments are more modern, developed in the early 20th century thanks to new synthesis methods in Organic Chemistry. These synthetic pigments now represent a very important group in the manufacture of colours for artists, producing bright and luminous tones of extraordinary intensity. The range of organic pigments is currently very extensive and includes azo pigments, phthalocyanine blues and greens, dioxazines, pyrroles, anthraquinones, quinacridones, and more.","brand":"Vallejo Colors","offers":[{"title":"Default Title","offer_id":61428508295498,"sku":"17821","price":36.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0999\/0963\/2330\/files\/vallejo-artist-acrylic-200ml-821.jpg?v=1774444914","url":"https:\/\/vallejocolors.com\/en\/products\/pintura-acrilica-naranja-pirrol-200-ml-bellas-artes","provider":"Vallejo Colors","version":"1.0","type":"link"}
