To expand those intellectual capabilities and help the brain grow coloring pages are a very good form of intellectual exercise. Occasionally, you'll find official cartoon or TV character sites (such as PBS programs) will make available coloring pages for free to their fans. And there are many other sites that distribute coloring pages of those copyrighted characters. Sounds like dangerous legal ground ...but, surprisingly, I've never heard of any of these sites being prosecuted for copyright infringement. So they'll probably continue to make them available. These sites are easy to find on the internet and they provide the child with a chance to explore his creativity. He is all by himself to experiment and learn. The shapes and colors will keep him busy and his mind occupied in making the best use of colors and drawings. Once the drawings are printed he can take them along to his room or to some other part of the house that pleases him. Coloring books also help teachers and parents to solidify children's knowledge. Children can be instructed in their colors, the alphabet, shapes, seasonal occasions, as well as spiritual education to be strengthened in church or at home.
According to Wikipedia: A coloring book (or colouring book) is a type of book containing line art for a reader to add color using crayons, colored pencils, marker pens, paint or other artistic media. Coloring books are generally used by children, though coloring books for adults are also available. They cover a wide range of subjects, from simple stories for children to intricate or abstract designs for adults. The golden age of coloring books is considered to be the 1960s. However, it is important to understand that using a coloring book for adults is not exactly the same as completing an art therapy session. While art therapy was first practiced in the 1940s, the first research on using adult coloring pages as therapy is generally believed to have only begun as recently the mid-90s. Some might think its crazy talk. Many more, however, have perhaps already realized the same.
