{"type":"firestarter.listing","listing":{"id":"lst_VykGK0Kt","product_name":"Doppler Blue","category":"PHYSICAL","description":"There’s nothing still about Doppler Blue. This rich multichrome eyeshadow pulses with movement, shifting from deep sapphire to teal, violet, and hints of smoky green. The color payoff is bold and dimensional, creating the illusion of motion as it catches the light from different angles.\nSleek in texture and dramatic in tone, Doppler Blue brings a cool, celestial energy to your look. Whether used all over the lid or blended into a smoky wing, it delivers intense color with a seamless finish.\nKey Features:\n\n\nMultichrome shift: Sapphire, teal, violet, and green\n\n\nBold pigment with ultra-smooth, blendable formula\n\n\nCreates a shifting, dimensional effect under any lighting\n\n\nHandmade, vegan, and cruelty-free\n\n\nPerfect for smoky looks, lower lash line drama, or dynamic liner\n\n\nNamed after the Doppler effect, the way waves stretch and shift through space, this shade echoes that same fluid transformation in color and depth.\nPro tip: Layer over a black or navy base to amplify its shift and create the illusion of endless depth. Use a tacky primer for maximum shine. \nApproved for Eye use.\n","images":["https://cdn.shopify.com/s/files/1/0071/8982/3539/files/DopplerBlue_masked.jpg?v=1750871962","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_ca48796e-5d1f-4937-baba-f9f5fadf21b8.jpg?v=1751049573","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":"2026-06-18T20:44:59.526Z"},"share_url":"https://firestarter.network/l/lst_VykGK0Kt","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
