Rainbow Over a Futuristic Space Colony

Ultra-detailed concept art scene inside a sprawling space colony hub. A vivid rainbow arches across a gigantic transparent dome, refracted by crystalline windows and solar sails, casting prismatic light on chrome walls, hover corridors, and lush hydroponic bays. In the foreground, astronauts in sleek suits and robotic drones marvel at the spectacle. Outside, a star-streaked void and a distant gas giant peek through the dome. Architecture blends modular habitats, curved transit tubes, and glass balconies. The atmosphere glows with teal and amber neon accents, dust motes illuminated by rainbow light, yielding a cinematic, painterly vibe with volumetric lighting. Style: concept art, matte painting, high-detail sci-fi, 8k.
