The Potato tubers have a beautiful earthy tone that is highlighted by a few darker spots. Their surface is smooth and free of blemishes, with a few small bumps here and there. The ends are pointed and the tubers are slightly curved, making them look even more inviting. To color this page, I would use a combination of light and dark browns. The lightest layer should be used to outline the shape of the tubers and give them a three-dimensional quality. From there, I would add multiple layers of subtle tones and further deepen the richness of the pigment. Finish it off with a few details like shadowing and accents of light brown to make them look even more realistic.
