This will help them to not only recognize different colors but to also learn the names of the different colors. Developing these skills will help in later development too as your child begins to learn to read and write. He or she can then learn how to write the names of all of the different colors. You see learning is progressive and incremental - it happens in stages. Step-by-step as I have described. This is the true beauty of learning...the more that your child puts in, the more they will get out of learning. As their knowledge grows, so will their interest in a range of different subjects.
The computer and the internet have opened an entirely new spectrum of coloring and drawing. Adults now make very sizable livings creating, drawing and coloring pictures for computer animation including video games, movies, commercials and items most adults would never consider, such as some high-quality information websites. With this option available as a full-fledged career for adults, it is no wonder that the tools and formats used in this style of artwork have carried down to children, albeit on a smaller scale.
Coloring in pages that are specific for coloring. I have found a few websites that have pages to color that are downloadable. You can also try a resource store for teachers. These specific pages for coloring are pictures or drawings of a variety of design that you alone enjoy. You can make your own coloring book with these pages. After coloring the designs you can write your own narrative about how you feel. Write how the design itself and the colors you used relieved your stress. You can even write a short story about the design if you like, this is your project and it is for your eyes only.
