The coloring page features a steam locomotive being pulled by a mole. The locomotive has a powerful and impressive presence, with its large body and many wheels. The mole looks steadfast and determined as it works to push the locomotive forward. Depending on the colors you choose, the page can look sophisticated, fun, and adventurous. For the mole, I suggest using a range of pinks and browns. To give the locomotive an extra dose of realism, color the smoke from the smokestack with light grays and dark blues. The locomotive body can look nice with shades of yellow, rusty oranges, and black highlights. Lastly, for the wheels, blend warm browns and crisp whites to add some depth.
