door-stop composite doors come in seven external colours; red, green, blue, black, white, oak and now also in darkwood. The internal colour is white.
The solid colours - red, green, blue, white and black - are pre-pigmented which means the colour is added during the manufacturing process. As the skins are applied, the colour goes on evenly.
The light oak finish is a hand-applied stained finish to give depth the woodgrain.
