PROMPT:
Create a hauntingly mesmerizing image depicting a decrepit, high-tech underground metropolis set in a dystopian future, where neon-lit advertisements and holographic projections pierce through the thick, grey fog that perpetually shrouds the crumbling infrastructure. Incorporate vibrant, electric hues of turquoise, green, and gold, while limiting the use of pink. The scene should exude a sense of foreboding, with twisted metal beams and rusted machinery scattered amidst the crowded, dimly lit alleys. In the distance, a colossal, cybernetic skyscraper rises, its peak lost in the perpetual gloom, as if it's piercing the very fabric of the fog itself. Ensure the image appears photorealistic, with meticulous attention to lighting, textures, and depth.
