No matter what the theme or the picture, all a child - or the young at heart - needs is the page and something to color with. Pencils, crayons, markers, watercolor paints, chalk. There are coloring books made specially to be used with water-colors, that come with their own little set of paints and brush, and have thicker pages.
Commercial use of color printing is prevalent in newspapers and magazines that make their material captivating for the reader using this means. It usually involves the customization of a printing press to automatically reproduce the headings, subtitles and other content features of a page in their correct color presentations. This is especially important in magazines, which rely almost entirely on colorful pages. The production of posters and outdoor billboards also rely on color blending to reach a certain visual effect. This is rather complicated for it is in full color impression, which is ideally achieved through the blending of three neutral hues with black. The technique is also applied in photography to give a full color impression on the whole page.
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.
