Buy the botanical study for the story. Keep it for the soft grey. The leaf is painted in loose watercolour washes, so the greys shift from pale mist to near-black without a hard edge anywhere. Put it up and a flat white wall gets depth without gaining colour, which is why it suits rooms that are already busy with texture. Hang it above a bed, a low sideboard or in a bathroom where the steam-and-tile look needs something living. Pair it with pale wood, black metal, linen and real plants. Don’t crowd it with strong colour prints or heavy patterned wallpaper the washes need white space around them to read properly. As a canvas the surface has a slight tooth, which suits the painted washes.
