This striking coloring page features the Operetta, a grand theater with a beautiful red and gold color scheme. The proscenium arch is decorated with intricate carvings, and ornate Corinthian columns support the balconies. Dazzling lights hang from the ceiling, casting an ethereal glow over the dark stage. To bring this striking scene to life, one could start with deep reds and golds for the walls, and then use softer shades for the statues and carvings. Blue and green could bring vibrancy to the Corinthian columns, and white or yellow would be ideal for the lights. The darker tones could add drama to the shadows and help to create an unforgettable image.
