This deck is uses the new Trex island mist color. It has a very pleasing mix of greys with a slight hint of light blues mixed in. We think the color is a very nice addition to the Trex Transcend tropical line of decking. As we do on all decks, we use hidden fasteners (Trex hideaway in this case) for the decking and we also use full length boards, running an expansion gap down the middle to avoid any butt joints.
