This rich color has very high opacity and a smooth texture.\nTrue Vermilion is a brilliant red pigment with a rich history of being used throughout history and around the world from Ancient Rome’s decorative arts and the illuminated manuscripts of the Middle Ages to lacquerware in China since the Song dynasty. It was even used as a rouge-like cosmetic in ancient West Asia. The pigment derives from the powdered mineral cinnabar, the most common ore for sourcing elemental mercury. The mineral is generally found in its bright scarlet-to-brick color and occurs in crystals that resemble quartz.\nHalf Pans contain around 2ml of paint and are approximately 3/4\" x 1/2\" x 3/8\" deep.\nColor Index number as provided by vendor: PR3\nPlease note that Rouge Vermilion is not 100% lightfast, and may fade over time in direct sunlight.\nAll of our watercolors handmade in our shop using the highest quality earth and synthetic pigments and natural watercolor binding medium made from gum arabic (sap from acacia trees), honey, glycerine and distilled water.\n All of our watercolors conform to ASTM D-4236.","images":["https://cdn.shopify.com/s/files/1/0631/2017/9426/products/Rouge-Vermilion_203e4878-44d6-4360-b8ef-6e7349dbcab5.jpg?v=1657762603","https://cdn.shopify.com/s/files/1/0631/2017/9426/products/Rouge-Vermilion-Square_5517c505-bcf2-4b28-bafb-642e936a85b7.jpg?v=1657762603","https://cdn.shopify.com/s/files/1/0631/2017/9426/files/Watercolor_Half_Pan_Trio.jpg?v=1773278386"],"price":6,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:22.449Z"},"share_url":"https://firestarter.network/l/lst_ZxBEMxDj","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
