This fun and vibrant coloring page features the four Ninja Turtles – Leonardo, Donatello, Raphael, and Michelangelo – standing side-by-side in their signature poses. They’re wearing their signature colors and the classic masks covering their faces. Behind them is their loyal teacher and mentor, Master Splinter. The bright colors of the page, coupled with its bold lines, invites creativity. We suggest using bright colors such as green for the turtles' shell and skin, purple for Donatello's mask, red for Raphael's, orange for Michelangelo's, and brown for Splinter's coat. To make the colors even brighter, use a high-contrast palette of blues, yellows, and oranges. Don't forget to add highlights and textures to make the colors pop. Finally, use a dark shade of grey or black to define the outlines and show-off the intricate details. Have fun and make it your own!
