Ultra-realistic 3D Visualization of a Futuristic Colony

Design an ultra-realistic 3D visualization of a futuristic colony established within a vast lunar crater. The scene should feature a lively central hub arranged in a symmetrical pattern, surrounded by glass-domed habitats, state-of-the-art research centers, and energy stations softly illuminated by neon lighting. Include rovers and humanoid robots interacting with scientists and engineers clad in spacesuits. Depict a modular spaceport with a streamlined spacecraft docked, accompanied by walkways extending to observation decks that provide views of the rugged lunar terrain. The lighting should recreate the sun's rays casting elongated shadows from the edges of the crater, while the textures of the lunar surface and colony structures should showcase intricate levels of detail, with metallic surfaces and subtle dust. Incorporate scattered advanced hydroponic farms enclosed in transparent domes emitting faint green light, and a backdrop of a star-filled sky framed by the faint atmospheric glow above the colony.
