The gray-scale print of these images is lighter than the bold lines of average coloring books by design so that the images look more like a photograph when colored in. The light backgrounds give each automobile great contrast and puts the emphasis on the car. Car enthusiasts and experienced colorists will find images of vintage hot rods, rat rods, and classic automobiles to bring to life with colored pencils, crayons, gel pens and other art media in the pages of this coloring book. Images are each a collage of digitally processed gray-scale photos of classic cars, local landscapes, and even a few four-legged sidekicks because what dog doesn't love a car ride.
