A bedroom this pared back can take one serious deep red. It only takes a thumbprint of it here, sitting under a slope of pine trees that fade off into fog, and that single mark is what pulls the whole wall together. Hung above a bed or a low chest of drawers, it gives a quiet room depth without adding noise or colour. Keep the space around it generous this one needs air on all sides to work. Pair it with pale wood, linen bedding, wool and matte ceramics. Skip busy patterns and shiny gold nearby; they fight the fog. On premium fine-art paper, the soft grey washes keep their subtle, papery finish.
