With a tree-lined avenue, scale decides whether the living room wakes up. Klimt's painted path pulls the eye deep into the picture, and a bigger size lets that view do the work of a window on a solid wall. The dusky greens and blue-violets calm a busy room without dulling it, and the small yellow house at the end of the trees adds a warm point of focus. Hang it above a sofa, a long sideboard or a reading chair. Pair with walnut or dark oak, linen or velvet, and stoneware in soft greens. Skip it if your room is already leaning hard into bright citrus or high-shine chrome.
