In the coloring page, four tanks are lined up in a row, with alternating gun barrels pointing to the left and right. The tanks are a mix of light and dark greens, providing plenty of opportunity to experiment with different shades. Against the backdrop of the deep desert landscape, the tanks look all the more impressive, the mountains adding the perfect finishing touch. To add more depth, you could use lighter tones in the background shading and darker tones for the tanks for a more intense look. Darker greens could also be used around the edges of the tanks to give them more definition. You could then use hues like yellow and orange to create a vibrant sunset scene in the desert sky.
