"Generate a bright, animated sky in the signature Disney Pixar style. The sky features a rich, vibrant blue with soft, fluffy clouds that have rounded, smooth edges. A warm, radiant yellow sun beams gently from one side, with soft sunlight illuminating the clouds and creating a magical, glowing effect. A colorful rainbow arcs gracefully through the sky, with rich, saturated hues that seamlessly blend into the soft, dreamy clouds. The style should emphasize Pixar’s signature animated look, with exaggerated, playful lighting and a sense of whimsy and charm. The entire scene should feel cinematic and filled with life, focusing purely on the sky with no other objects or landscape elements."
