A coloring book is a type of book containing line art to which people are intended to add color using crayons, colored pencils, marker pens, paint or other artistic media. Traditional coloring books and coloring pages are printed on paper. Coloring books are a form of adult therapy that has seen a growth in popularity in the 2010s. They reportedly bring people a sense of their childhood, and help with developing fine motor skills and vision, reducing anxiety and creating focus, and relieving stress and anxiety in a manner similar to meditation. Concentrating on coloring may facilitate the replacement of negative thoughts and images with pleasant ones. Coloring books can be used in daily activities. They are also used in rehabilitation of accident victims to aid recovery of hand-eye coordination, and they are used with autistic children both for entertainment and for their soothing effect.
