A children's coloring book is a book filled with black and white outlines of pictures, illustrations or scenes for kids to color in. The pages can be made of thick or thin paper, and can be bound together in a book format, or loose sheets.
The coloring book can feature a variety of themes, such as animals, nature, fantasy characters, vehicles, or even popular children's TV characters. The images can range from simple shapes and designs to more detailed and intricate illustrations, depending on the age group and skill level of the intended audience.
