{"type":"firestarter.listing","listing":{"id":"lst_SGpMdJl9","product_name":"Spectral Shift","category":"PHYSICAL","description":"There’s a quiet coolness to Spectral Shift, but the impact is anything but subtle. This multichrome eyeshadow moves through steel blue, soft gold, olive green, and hints of smoky violet. The effect is mysterious and sophisticated, like watching light scatter across distant ice fields.\nThe formula is ultra sparkly, versatile, and easy to layer, making it ideal for everything from soft, dimensional washes to full-intensity, multi-tonal glam.\nKey Features:\n\n\nMultichrome shift: Steel blue, gold, green, and violet\n\n\nMedium-deep base with a refined, fluid shift\n\n\nCreamy, buildable texture that works on all skin tones\n\n\nHandmade, vegan, and cruelty-free\n\n\nGreat for moody gradients, lower lash accents, or soft smoky lids\n\n\nInspired by the way light disperses across a spectrum, Spectral Shift captures quiet drama and subtle complexity in a single swipe.\nPro tip: Use over a gray or black base to amplify its cooler tones, or layer over a shimmer for a more ethereal finish. Use a tacky primer for maximum payoff and shine. \nApproved for Eye use.\n","images":["https://cdn.shopify.com/s/files/1/0071/8982/3539/files/SpectralShift_masked.jpg?v=1750872649","https://cdn.shopify.com/s/files/1/0071/8982/3539/files/IMG_6451_17MP.jpg?v=1751051407","https://cdn.shopify.com/s/files/1/0071/8982/3539/files/Swatches1IMG_0018labeled_c1a51aab-6d8a-49cf-afa9-8d22b1c83292.jpg?v=1751049630","https://cdn.shopify.com/s/files/1/0071/8982/3539/files/Swatches.png?v=1751051407"],"price":18,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-18T20:44:59.520Z"},"share_url":"https://firestarter.network/l/lst_SGpMdJl9","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
