Generate a vibrant, dreamlike landscape of a futuristic city on a planet with an atmosphere that shimmers like iridescent opal, featuring a stunning, floating, rainbow-colored unicorn that breathes stars and constellations, surrounded by towering crystal spires that reflect colors of sapphires, emeralds, and amethysts, under the radiant dual suns that set the sky ablaze in hues of peach and lavender.
