Example of Color Variation
Take, for instance, a manufacturer of vinyl siding and guttering. They may have half a dozen color choices for their customers. In our experience, as they produce materials, the colors are slightly different from run-to-run. Some are a little darker or have a trace more of yellow. Whether the caulking we produce now will match the same manufacturers' siding in three months is difficult to say. However, we can confidently say that the color will still be far closer than anything you can buy at the hardware store. In addition, the slight difference in color may not even be visible except on very close scrutiny.
Other Factors with Color
Other factors such as age, exposure to sunlight, and surface texture all come into play as to how we perceive color. Most of the time, this will not make a difference in the choice of product. However, we don't want to misrepresent ourselves. Instead, we want to educate you about the quality of our products and their intended uses.
