There is a product called exact color caulk that you can add paint to and have it match that paint. So if you can find a paint color that matches your grout you can add it to this caulk to get a match. Our carpenter used it in our kitchen. This is a link http://www.sashco.com/products/exact-color/

Hi Casandra!

We apologize for the inconvenience, but Smoke is a custom color made exclusively for Lowe's, and only sold in our Keracolor grout products.

The two closest colors in our standard caulk/grout color palette to Smoke are:
#77 Frost (about one shade lighter)
#93 Warm Gray (about one shade darker)

If you decide to try one of the above colors of caulk, and the color does not match to your satisfaction, please give us a call at 1-800-992-6273 so we can offer up another solution.

Thank you very much for choosing MAPEI!
