‘Too safe,’ said nobody standing in front of warm mustard yellow. This illustrated Vietnam street scene brings sunshine, old shutters and a slow afternoon walk to a quiet wall. The buildings glow against a soft sky blue, with sage trees and a rust-roofed terrace anchoring the bottom half. Hang it in a hallway, kitchen or study where you want a little holiday feeling every morning. It sits well above a console, a small dining table or a writing desk. Lean into pale oak, rattan, linen and cream walls. Skip very cool grey schemes and busy patterned wallpaper next to it the lettering and architecture need a calm wall to do their job.
