A coloring book (or colouring book, or colouring page) 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 or card. Some coloring books have perforated edges so their pages can be removed from the books and used as individual sheets. Others may include a story line and so are intended to be left intact. Today many children’s coloring books feature popular cartoon characters. They are often used as promotional materials for animated motion pictures. Coloring books may also incorporate other activities such as connect the dots, mazes and other puzzles. Some also incorporate the use of stickers.
The addition of colorants to foods is thought to have occurred in Egyptian cities as early as 1500 BC, when candy makers added natural extracts and wine to improve the products’ appearance. During the Middle Ages, the economy in the European countries was based on agriculture, and the peasants were accustomed to producing their own food locally or trading within the village communities. Under feudalism, aesthetic aspects were not considered, at least not by the vast majority of the generally very poor population. This situation changed with urbanization at the beginning of the Modern Age, when trade emerged—especially the import of precious spices and colors. One of the very first food laws, created in Augsburg, Germany, in 1531, concerned spices or colorants and required saffron counterfeiters to be burned.
