Cerulean to Sienna Gradient in Sydney Atrium

Dim twilight falls through high windows into a vaulted Sydney atrium, illuminating a large abstract panel where cerulean blue transitions smoothly into burnt sienna. Polished stone floors reflect small, sharp highlights from nearby interior lamps, scattered points of brightness against the deepening shadow. The color gradient dominates the frame, surrounded by generous negative space that outlines the wall's curvature. Late summer light softens the architectural lines as the hue shifts across the surface. A faint reflection of the blue rests on the glossy baseboard at the bottom edge.
