This book is an adult coloring book with color by number. It's actually for people of all ages and is designed for beginners or those looking for easier (not so busy) designs to color. For each design there are 3 pages: a numbered version of the design, and un-numbered version of the design and a swatch page. The swatch page is designed to let you experiment with different color combinations. There are the numbers listed with a suggested color. There are also 2 quarter sections of the design to encourage you to experiment with your own color combinations. The numbered design page is the color by number page so you can use the colors suggested on the swatch page or those you decided to use. (Note the numbers will show through.) The third page is an un-numbered version of the design. This page is designed so you can color the design without having numbers show through or for those who don't want to use the color by number approach. The back cover has a list of the color names and an example of each color. The names listed are from Berol Prismacolor pencils. These are really nice expensive pencils. It is recommended to just pick any brand of colored pencils and just match those pencils to a color listed. Stress relieving. EXCELLENT for BEGINNERS
