Vibrant Spiral Staircase in a Lighthouse, Seen from Below

Inside a lighthouse, a vibrant spiral staircase winds upward around a central cylindrical column. The image is viewed from the bottom, looking up along the colorful steps as they ascend toward the warm glow of the lantern room. Each tread is lacquered in a bold color—crimson red, electric blue, sunny yellow, and emerald green—forming a vivid rainbow around the white, weathered stone walls. A brass handrail loops in a tight spiral, catching glints of light. Porthole windows reveal a seascape with crashing waves and a bright sky. Beams of sunlight filter through upper windows, casting dramatic long shadows and a glowing aura on the glossy steps. The composition emphasizes dizzying height and geometric spiral, with a sense of motion as if the stairs are guiding the eye toward the beacon above. Photorealistic, high-detail, cinematic lighting.
