This large, dark gray tank sits imposingly in a lush green field. Its wide body and two large treads suggest a formidable presence. The turret on top of the tank has a long, menacing barrel that shows formidable power and strength. To bring out the varying tones of the tank, give it some shading to make it appear three-dimensional. Some muted colors such as soft blues, dark greens and browns will be effective in making the tank stand out against the bright green of the grass. You could also utilize bright colors—blues, greens and yellows—for the turret to make it look more vibrant. There could also be some detailing work done to make the design more interesting. Overall, this coloring page has potential in giving a realistic, powerful look for any coloring enthusiast.
