This coloring page features three bright and cheerful fruits: a green apple, a red apple and a yellow banana. The white background creates a nice contrast against the vibrant colors of the fruits, making them stand out even more. I would make the apples a bright, juicy red and green, respectively. I would make the banana a pleasant light yellow. For extra emphasis, I would also use different shades of each of the colors to create texture and shadows. This would create a beautiful, realistic image of the fruits. All of these colors really help bring the image to life!
