A watercolor painting of a scientist inside a futuristic portal chamber. Use soft washes and wet-on-wet techniques with colors that bleed into each other. A circular portal at the center glows with blues, purples, and greens, casting a luminous light across the scene. The scientist wears a white lab coat and safety goggles pushed on the head, standing at a console with glass and brass panels, adjusting a lever. The chamber is ringed with chrome rings, glass walls, and holographic readouts; mist and vapor drift through the air. The mood is ethereal and contemplative, with delicate textures, subtle linework, and atmospheric reflections from the portal’s glow.
