Every coloring page in the app, drawn from the image files that ship with it. Each page comes in a wide and a tall version, and each version has four layers: a pen outline, a chalk outline for night mode, and one colored fill per theme. Pick a category, then switch views to check each layer on its own or stacked the way the app draws it.
