{"type":"firestarter.listing","listing":{"id":"lst_eNLhr7vR","product_name":"CfM Emerald","category":null,"description":"Years and years ago, when we were a young shop with a wee handmade watercolor collection, a friend who'd been traveling through Italy was sweet enough to bring back some pigment for us as a gift. We fell IN LOVE with both the brightness and depth of that special color, but were a little deflated when we discovered how tricky it was to mix into watercolor. For a long while we kept in on our shelf out of sheer admiration, but knew someday we'd need to go for our own version. And so it happened one glorious afternoon: the perfect glowy green to fit alongside CfM Pacific and Turquoise Lake, as a lovely trio of greens on the bluer spectrum!\nThis blend contains a fair amount of fluorescent pigment which makes it not lightfast.\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/CfMEmerald.jpg?v=1675809952","https://cdn.shopify.com/s/files/1/0631/2017/9426/products/CfMEmeraldsquare.jpg?v=1676412566","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":"2026-06-18T20:47:22.201Z"},"share_url":"https://firestarter.network/l/lst_eNLhr7vR","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
