{"product_id":"ultramarine-blue-very-dark","title":"Ultramarine Blue, very dark","description":"\u003cp\u003eUltramarine Blue delivers the luminous, saturated hue that has defined this pigment for centuries. This very dark formulation maintains the characteristic brightness ultramarine is prized for, while offering depth suitable for shadows and rich color mixing. Non-toxic and exceptionally lightfast, it performs reliably across watercolor, oil, acrylic, and most traditional media. Note that ultramarine has limited alkali resistance and may gray slightly in acidic environments—ideal for artists who understand its nuances and want authentic, museum-quality color.\u003c\/p\u003e","brand":"Kremer Pigments","offers":[{"title":"100 g","offer_id":44482282684486,"sku":"45000.12100.136","price":10.0,"currency_code":"USD","in_stock":true},{"title":"1 kg","offer_id":44669975035974,"sku":"45000.13010.142","price":51.0,"currency_code":"USD","in_stock":false},{"title":"10 kg","offer_id":44669975068742,"sku":"45000.13100.152","price":545.75,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0676\/5009\/3126\/files\/45000_4.jpg?v=1779117077","url":"https:\/\/www.newyorkpigmentco.com\/es\/products\/ultramarine-blue-very-dark","provider":"New York Pigment Co.","version":"1.0","type":"link"}
