PROMPT:
Create an intricately detailed and photorealistic image of an underground metropolis, hidden beneath the earth's surface, where a labyrinth of tunnels and caverns converge, illuminated by a kaleidoscope of vibrant colors, with bursts of emerald green, sapphire blue, and amber orange, reminiscent of a gemstone cache, while avoiding the use of pink hues, instead, opting for a rich tapestry of iridescent blues, golds, and turquoise, evoking a sense of mystique and wonder, as if discovering a long-lost civilization, where ancient architecture blends seamlessly with modern innovations, and the air is alive with an otherworldly energy.
