Superman flying beside a rainbow for coloring

This whimsical illustration features Superman soaring effortlessly through the sky, flying beside a vibrant rainbow that arches across the scene. To make the rainbow the focal point, color each stripe in the traditional order: red, orange, yellow, green, blue, indigo, and violet. The sky should be a light blue gradient with fluffy white clouds. Superman’s suit should maintain its classic heroic colors: deep blue for the body suit, bright red for the cape, and golden yellow for the emblem. To add depth, use darker tones for shadows on Superman and lighter colors to highlight the folds of his cape. This creates a dynamic and colorful scene that captures Superman’s grace and power.
