魔法畫筆改變黑白世界

An enchanting scene depicting a young girl in a black-and-white world holding a magical paintbrush. As she waves the paintbrush, vibrant and colorful elements appear in her wake, creating a road, trees, and birds in a watercolor style. The contrast between the grayscale environment and the vivid, flowing colors emphasizes the transformative magic of her art. The girl is dressed in simple black-and-white attire, with her expression full of wonder and joy. The composition highlights the transition between monochrome and colorful, with soft, fluid watercolor effects bringing the scene to life.
