As a child, the only concern is to play and find many things to play with and to keep you entertained. Especially parents are always looking for ways to educate their children, to teach them interesting thing while they are playing. Out of all our activities from childhood, we always remember with pleasure about the coloring books. They are definitely a passion for most of the children, an activity used both in kindergarten and school, but also a great activity for home entertainment. In this institutions coloring pages are used for educational purposes, in order for the children to develop their imagination, to improve their memory, but also as an enjoyable activity to share with friends and colleagues. Whether they were fairytale characters, animals, cartoon characters, numbers, coloring books always kept us company, especially in the long winter days, when we spend most of our time indoor. Is that way how we learned the colors, the name of the animals, and we have developed imagination.
