A color guide for paint-by-numbers is perhaps the most indispensable of all aids. It describes every number which is located on the canvas and the color that corresponds to it. Some higher level guides enable users to mix colors which adds an element of creativity. The guide helps the artist create more beautiful artworks using the paint by numbers method. For instance, it can suggest the use of complementary colors or colors that sit next to each other on the color wheel. It is an exceptionally valuable tool, especially for novice users learning color theory through paint-by-numbers.
