Rainbow in a Cartoon Laboratory

A vivid, whimsical cartoon-style laboratory scene featuring a luminous rainbow arching across the ceiling, casting rainbow light on a bright workbench. A cheerful scientist with oversized eyes, wearing a white lab coat, safety goggles, and blue gloves, stands mixing glowing liquids in beakers and test tubes. The bench is cluttered with labeled jars, bubbling flasks, a microscope, pipettes, and a chalkboard filled with cute doodles and simple formulas. Shelves behind hold assorted glass containers and colorful tubes. The art uses bold black outlines, flat saturated colors, and simplified shapes for a playful, kid-friendly look. Soft shadows, warm studio lighting, sparkles around the rainbow, and a friendly, upbeat mood.
