Fire Rainbow Arc Over Granville Island Thunderheads

A brilliant fire rainbow arcs sharply across a cloudless blue sky, its spectrum of red, orange, and yellow bands glowing intensely against the backdrop of stacked thunderheads. Below the horizon, dark gray cumulonimbus towers rise in heavy layers, their bases heavy and textured with shadow. The bright midday sun illuminates the scene, making the ice crystals in the high cirrus clouds refract light into a vivid, fiery band. The contrast between the warm spectral arc and the cool, menacing storm clouds creates a dramatic visual tension. In the foreground, the dark rooftops and industrial structures of Granville Island anchor the view, their metallic surfaces reflecting the harsh daylight. The sharp edges of the storm clouds meet the smooth curve of the rainbow, highlighting the distinct separation between the high-altitude ice phenomenon and the low-level precipitation.
