17. Midnight Black Venetian Plaster
For the ultimate expression of dark drama, a midnight black Venetian plaster wall is unmatched. Because the plaster is applied by hand in multiple layers and then polished, the final surface has an incredible depth that looks almost like obsidian or polished volcanic rock. It does not absorb light the way flat paint does; instead, it reflects it softly, showing off the unique, hand-crafted texture of the plaster. Pair this with minimalist furniture and a single, dramatic piece of abstract art.
