At night the stunning daytime colors gave way to black and white chiaroscuro. Electric lights outlined the silhouette of the Spreckels Organ Pavilion. Along the main avenue, more than 1,000 lamps with pear-shaped globes on stately pillars, and bracket lamps and braziers in the arcades, gave the buildings a soft glow. The haunting Churrigueresque relief of the Prado buildings was at its best at night under a full moon.
