This beautiful purple and white unicorn is perched upon a colorful rainbow cloud. Its long mane is flowing in the wind, and its magical gold horn glimmers in the sunlight. In its mouth an equally magical wand, ready to grant any wish, shimmers with possibilities. To color this scene, I would use light purples, whites, and pinks for the unicorn's mane and body, and blues and greens for the rainbow cloud. The wand, horn, and any stars or sparkles can be all shades of gold. Finally, a bit of yellow or a lovely shade of orange makes the sun shine brightly in this magical setting.
