On the coloring page, the boy and girl stand in the center with big smiles across their faces, surrounded by a faint pink background. The boy stands at the back gazing protectively at the girl, his hand gently resting on her shoulder while she looks at a vibrant, yellow bird in a cage held in her hands. The bird is thoughtfully looking back at her, and its beautifully detailed feathers have an orange and yellow tinge.
When coloring this page, I'd suggest a light pink for the background to add a subtle, comforting feel. Shades of blue could be used for the boy's shirt and jeans, along with some white for his shoes. For the girl, try using various shades of green for the dress and yellow for the bird's feathers to create a splash of warm color across the image. Finally, shades of pink and white would be great for details such as the girl's ribbons and the book's cover. I'm sure the end result would be a beautiful and cheerful illustration!
