The scene in this coloring page is a set of four tanks in various sizes and colors. The largest tank is in the front, and the other three tanks are located behind it. All of the tanks have a unique design and detail. The main tank is a bright shade of red, while the other three tanks are painted in shades of yellow, blue, and gray. To bring the page to life, try coloring the tanks in multiple complementary colors. Maybe shade the red tank in shades of orange and pink, the blue tank in shades of light blue and turquoise, and the yellow and gray tanks in shades of yellow and gray. Alternatively, color all four tanks in surprisingly monochromatic shades. Contrast this by making the largest tank the darkest shade, and the other smaller tanks the lighter shades. Whichever idea you choose, the page should come alive with vibrance and interest.
