This beautiful coloring page features a large cargo ship docked at a port. Brightly colored containers are already stacked on the ship's deck, while a crane is busy lifting more containers off the ship and placing them on the dock. To bring this scene to life, you could use blue or green hues to color the ship and the sea, while giving the port a vibrant orange or yellow tone. The containers can range from light to dark tones of blue, to represent the variety of color at the port. Finally, you could use whites and grays to color the crane and the smoke drifting up from its exhaust.
