What’s the study missing? Pitch green with some nerve. Most rooms full of books and paperwork have nothing on the wall that means anything, and this one instantly does. Once it’s up, the eye goes straight to that green rectangle in the middle of all the soft grey, and the whole wall gets a focal point without getting loud. Hang it at eye level behind a desk, along a hallway, or in a pair with another ground you’ve stood in. Keep the surroundings simple: painted walls, oak or walnut furniture, leather, wool. What it doesn’t want is a wall crowded with team shirts, scarves and signed memorabilia jostling for the same attention. Let it be the one considered thing in the room. As a canvas the washes read softer and the edges melt into the wall.
