Vibrant Geometric Staircase in Modern Interior

Ultra-modern interior staircase unfolding within a sunlit atrium. A geometric wall behind the stairs is composed of interlocking colorful panels in bold hues—magenta, electric blue, teal, lime, sunny yellow, and rich purple. Panels feature triangles, hexagons, and diamonds in a dynamic tessellation. The staircase has cantilevered wooden steps with a subtle grain, a brushed aluminum handrail, and hidden LED underlighting along each tread. Neutral concrete or white plaster walls, floor-to-ceiling glass revealing a hint of an urban view. Natural daylight from a large skylight casts crisp shadows and reflections on glossy wall panels. Perspective: low-angle, looking upward to emphasize depth and the wall geometry. Style: photorealistic 3D render with high detail, glossy finishes, and vibrant color accuracy.
