The five tanks in this coloring page look ready for some action! The small tanks are positioned neatly in a single row, with the yellow, large tank taking pride of place in the middle. The four small tanks are bright and vibrant, coming in shades of white, blue, green, and red. The large tank is a brilliant yellow, whilst the others provide the perfect contrast. This page would look fantastic colored in with some bold, vibrant shades. Why not make the smaller tanks a deep blue, a forest green, a scarlet red, and a natural white? Then, let the bold yellow of the large tank really stand out.
