Since the plugs are made directly from the deck boards, we do not recommend going with a "similar" color, as they will certainly stand out (almost like a "polka-dotted" look). Because Trex Enhance deck boards do not allow for the use of plugs due to their scalloped profile, we recommend using color-matched screws. The Starborn Industries color match for Trex Enhance Rocky Harbor is 'Warm Gray'. Starborn's [Cap-Tor xd](https://www.diyhomecenter.com/starborn-industries/cap-tor-xd) in Warm Gray would be the product we recommend for your deck. Good luck!
