This happy, round green creature sitting in the center of the page is begging for some color! You could give it a bright and cheery appearance with yellows, oranges, blues, and purples, or a softer and dreamier look with pinks and light blues. The object's nose and mouth can be brought to life with dark hues like browns and blacks, while its eyes can be allowed to sparkle when colored with lighter shades like silver and gold. Its ears, whiskers, legs, and feet could be easily shaded to complement its body in shades of black or brown. Finally, the entire page could be unified if a light tint of color such as pink or yellow is used as a background!
