The turtle in this coloring page looks like it's ready for a battle! Its blue mask and shell make it look both tough and graceful at the same time. The two swords in its hands give the impression it is a fierce warrior, making sure to protect its surroundings. To color this fierce turtle and bring it to life on paper, the best way to go would be to create contrast. Using darker shades of blue for the mask, shell and swords and a lighter shade of blue for the background is one way to make this image really stand out. You could also add some color to the eyes, to really make it stand out. Adding yellow and green, for example, can give this image a pop of color and a unique personality.
