This unique coloring page includes a diamond-shaped object with a face on it. The face has a prominent nose and small eyes, framed by a big smile with sharp teeth. The face is shaded green, and it is topped with a purple hat that has a yellow feather on it. To emphasize the comedy of the image, try coloring the hat a vibrant shade of purple and the feather a sunny yellow. Use lighter hues to indicate the round shape of the nose and the subtle lines around the eyes and mouth. You could also make the teeth white to increase the contrast with the face. Finish off the look with a lime green outline around the edges of the diamond.
