There are rare instances of contour drawings of famous architectural structures and monuments with a variety of parts made in a realistic manner. Such coloring is complex to implement and is designed for adults.

Coloring appeared in the United States as part of the "democratization of art", inspired by a series of lectures by British artist Joshua Reynolds and the works of the Swiss educator Johann Heinrich Pestalozzi together with his student Friedrich Friedrick Frobel.
