This coloring page has four large grey tanks standing in the center. At the top of each tank, there is a small black hatch. The tanks are connected to a larger grey pipe which runs from each one and continues down to the ground. Beside each tank, there is a small black platform, and a thin ladder running up beside it. To complete the scene add a splash of color. Use blues, yellows, and greens to add a vibrant touch. For a realistic effect, create shadows and highlights on the tanks and pipe. You can also give the ladders a metal look with silver or grey hues. Have fun and get creative with this scene!
