The Color Me Adult Coloring Book series are coloring books developed specifically for adults. "Color Me Space" includes images of our exploration to places off of our fragile Earth. The images are more than simple outlines; set up to be colored in or painted on as you desire. Each image is my individual creation, and will not be found in coloring books designed for kids. Level 4 books include limited solid outlines and more faint rough guidelines, allowing you to provide your own interpretation of background images. The images are printed on white bond paper, ready for crayon, color pencil, charcoal, or paint.
