The coloring page shows a car on the side of the road with a disappeared wheel that is missing. The tire is completely flat and the rim is bent, revealing just how serious the accident must have been. I would color it with muted blues, greys, and browns to reflect the aftermath of the accident. The car itself might be blue or grey, while the tire rim and the tire itself could be a light brown or tan and the flattened tire could have a darker brown outline to indicate it's flatness. For the background, I would use cool blues, greys, and whites. If I had the space and the time, I would also add a few more details such as streetlights, street signs, or trees on the edge of the road to give more context to the image.
