PROMPT:
Create a photorealistic image of a mysterious, grandiose opera house at night, radiant with vibrant colors, particularly emphasizing emerald greens, sapphire blues, and amber tones, while minimally incorporating pink hues. The opera house's ornate facade should be adorned with intricately carved stone figures, delicate filigree, and majestic staircases, evoking the opulence of a bygone era. In the foreground, a lone, masked figure in a flowing black cape stands at the top of the grand staircase, gazing out into the night, surrounded by an aura of mystery and allure. The atmosphere should exude drama, romance, and an air of secrecy, transporting the viewer into the realm of the Phantom of the Opera.
