It's actually the natural wood color. Ipe mixed with Grappa and natural tone.

To achieve this deck's look, Seal It Green Xtreme Exotic Sealer in Clear Tint was used. Although it is a clear treatment, the tint applies as brown but dries clear. This allows for maximum SPF protection and enhances this deck's Ipe wood color's natural tone that no other sealant can provide. We have tried many sealants out there, but found Seal It Green Xtreme Exotic Sealer enhances Ipe and Grappa wood better than anything out there. They also have a wide variety of other sealants that will treat all deck surfaces from bamboo, thermal wood, plastic/composite, and all others including treated.
