This coloring page features a young boy standing in front of an adorable rat that is in a scabbard. The boy has shaggy red hair and glasses, and is wearing a blue shirt with a light brown jacket. To add some color to this scene, the boy's shirt and jacket could be filled in with a bright primary blue and the rat's scabbard could be filled with a warm, earthy brown. The boy's hair could be shaded in with touches of yellow and orange, while his glasses can be colored in with metallic hues. The rat itself can be made more life-like with gentle pinks, browns, and grays. Finally, the background can be filled in with light, airy yellows and whites to create a lively atmosphere.
