A color blend is a combination of two (2) or more colors to achieve a random color effect. It is IMPORTANT to note that selecting a color blend is NOT like selecting ceramic tile. With ceramic tile you choose a pattern and a color and all tiles are identical. With paving stones, a color blend simply put, means the colors comprising the blend.
You will see paving stones that are completely solid in color, paving stones that have more of one color than the other and vice versa. To achieve an even blend throughout the installation, your installer will select various stones from a variety of bundles and lay them in a random manner to achieve a pleasant visual effect. (Imagine making a marble cake. You start with a completely yellow batter; slowly you add some chocolate and stir.
While adding the chocolate the appearance of the batter changes. If you would add a lot of chocolate and continue to stir you would have a completely chocolate batter. This applies in theory to paving stones and color blends. Your materials will range in color like the marble cake from solid yellow, to a lot of yellow and a little chocolate, to more chocolate and a little yellow, to completely chocolate.)
**It is important to understand that unless you are seeing a complete project, the sample patterns from which you are making your color selection, are hand selected solely to show the colors comprising the specific blend. Your materials may vary from samples you see. This is nothing to be concerned about. (see #4)
