{"type":"firestarter.listing","listing":{"id":"lst_hUJ3d3OT","product_name":"CfM Shadow Blue","category":null,"description":"This ethereal blue was inspired by atmospheric perspective, and the specific color of mountain ranges fading into the distance. Our atmosphere scatters blue light, which is why objects in the distance appear so blue—the further back they are, the more we see them with reduced clarity, value and color saturation! Like CFM Payne's Grey—Shadow Blue's darker, moodier sibling—CfM Shadow Blue is also a great alternative to black for portraying shadows.\nAll of our watercolors are handmade in our shop using the highest quality earth and synthetic pigments, plus natural watercolor binding medium made from gum arabic (sap from acacia trees), honey, glycerine, distilled water, and a dash of clove oil for freshness!\nHalf Pans measure ~3/4\" x 1/2\" x 3/8\" and contain ~2ml of paint.\nOur custom blended colors don't have a Color Index number, as they consist of a unique blend of two or more pigments. All of our watercolors conform to ASTM D-4236.","images":["https://cdn.shopify.com/s/files/1/0631/2017/9426/products/CfM-Shadow.jpg?v=1653564947","https://cdn.shopify.com/s/files/1/0631/2017/9426/products/CfM-Shadow-Square.jpg?v=1653565837","https://cdn.shopify.com/s/files/1/0631/2017/9426/files/Watercolor_Half_Pan_Trio.jpg?v=1773278386"],"price":12,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:47:23.093Z"},"share_url":"https://firestarter.network/l/lst_hUJ3d3OT","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
