This coloring page of Shrek and Donkey shows them looking straight at the viewer - Shrek is a large, green ogre and Donkey is a small, brown donkey. They stand next to each other, both looking serious. To highlight their friendship, one might color Shrek in earth shades of green and Donkey in more vibrant pinks and blues. For an extra fun touch, adding some accessories like hats or scarves may be a great way to make these two characters stand out. Bringing in some variety in textures and shapes can also create a charming dynamic that can bring a lot of life to the coloring page. Finally, adding the background with a combination of warm and cool hues can give the scene some dimension and realism.
