The coloring page depicts a young girl delivering parcels on a scooter around a bustling city. With a wide grin on her face, she looks like she's having the time of her life as she effortlessly moves from sidewalk to street, going in-and-out of traffic and weaving between crowds of people. To bring this scene to life in color, I would use bright and cheerful colors like yellows and pinks to evoke the joy of the scene. I'd blend blues and greens for the street and sky and pop in some smatterings of oranges, reds and purples to represent the festive energy of the city. For the girl, I'd choose cheerful pinks and purples to capture her joy and energy. Finally, I'd use a more neutral shade like brown to create contrast and bring the details of the scooter to life.
