Give the plain off-white feature wall one hard decision, and let everything else relax. This is a big leaf study cut through with bright pink, yellow and lilac over deep green, and it sets the colour temperature for the whole room. A quiet sofa, a plain rug and one lamp suddenly look intentional rather than unfinished. Hang it where people sit down: above a low sofa, behind a desk, or on the empty stretch of wall opposite a window. Pair it with linen, pale wood, black metal and simple stoneware, and keep a few real plants in the same corner. Don’t crowd it with other colourful pieces or busy wallpaper it needs clear space either side to work. Printed on premium fine-art paper, with the option to frame in real wood.
