Abstract celestial composition inspired by a potassium reaction transformed into a flowing nebula vast, seamless gradients of deep midnight indigo dissolving into warm gold, aged cream, pale peach, muted teal, and faint coral. Luminous clouds of pigment drift, fold, and softly collide like a star system forming; diffuse radiant centers, vaporous wisps, mineral dust, delicate stellar specks, and atmospheric pools of light. Prioritize smooth flowing color transitions and layered luminous texture over recognizable objects, symmetry, explosions, or hard geometric shapes. Elegant vintage print character: subtle screenprint grain, gentle halftone noise, weathered paper texture, restrained ink bleed, sophisticated editorial-art-poster feeling. Deep, nocturnal, mysterious, glowing. No text, no letters, no numbers, no logo, no watermark, no planets, no spaceships, no literal galaxies. --ar 2:3 --stylize 650 --chaos 12 --v 8.2
