Pigment provides more than 10,000 images for anybody to color; more than enough, one would think, however there are also many people on it who create their own artwork to color.  Most of these people share those designs with the community, making them free to color to anybody.  Admitedly, it is a little bit of a rigamorole to do this.  One first has to share the image by emailing it to yourself, then save it as a jpg, import it into your photos’ program (Photos for the Mac; no idea what it’s called for PC’s); and, then, finally import it into Pigment, so you can start coloring.

Many , if not all, of the artists who do this are staggeringly accomplished, and, on this page are links to pieces by them that I’ve colored.  Each artist has their own page.  Enjoy.
