Traditional brick colors are red and stucco cream, however, there are many different ways to make colorful and decorative bricks. The easiest way to make a colored brick is to use colored rock in the mix before firing. Using this method you are limited to the colors found in natural rock composition. If you want something a little brighter or more unusual you can also apply pigmentation to the
. mix from virtually any source. Plant dyes and synthetics can both be used for the purpose. For a more artistic coloration you can also apply what is called a coating to the bricks before they are fired to give them a glazed or layered appearance. These coatings can be anything from sand to colored slurries. The possibilities are only limited by your imagination.
