The Barbie doll in the coloring page looks beautiful and serene as she holds a cute bouquet of flowers in her arms. She is wearing a frilly pink dress, with a dainty bow at the back. Her blonde hair is in two adorable pigtails, enhancing her youthful and cheerful look. I would paint the doll in shades of pink and white, giving her a soft and girly feel. For the bouquet, some sunshine yellow and grassy green is perfect for expressing the beauty of flowers in the garden. To deepen the contrast, a deep purple in her dress or a deep pink in her hair can really draw attention and tie the page together.
