This coloring page features three broken down robots, their heads tilted in different directions and their mouths hanging open as if they are crying. Amidst the robots are a slew of garbage and debris, including discarded pieces of cable and wires in a variety of shapes and sizes. I would suggest coloring the robots silver, with a hint of rust around their joints for a distressed look. Add an orange hue to the pieces of garbage to make it stand out. The background can be a light shade of blue to bring out the sadness of the robots. Finally, highlight the eyes of the robots with a few tear-like splotches of light blue and make their cheeks a deep red, showing their sorrow in contrast to their otherwise mechanical composition.
