The girl in the middle of the page stands with her arms crossed and her head tilted to one side, as if she is looking at something off to the side. She is wearing a vibrant red pair of trousers and a light blue shirt with pockets across the chest. The background is simple—a light yellow backdrop with white polka dots, and a pattern of overlapping grey and orange circles.
To begin coloring this page, I would start with the girl in the center. Her outfit can be painted with a range of bright colors, like oranges, yellows, blues, and purples, adding a bit of sparkle here and there. To contrast the vibrant colors of her clothing, the girl can be painted with soft pastel oranges and pinks. To add a bit of texture, I would use a thick, dark brown to paint the pockets on her shirt.
The background is perfect for using darker, bolder colors and patterns. Deep blues and greens will look great for the gray and orange circles, and a bright yellow will make the polka dots pop. To finish the page, outline the figures in the picture with a bold black pen. This will draw attention to the main figure and create more visual interest.
