‘Too safe,’ said nobody standing in front of deep navy. The blue here is banded and blocky, so the wall stops being a background and starts doing some work. Put it up and a quiet room gains a clear vertical line and a cool, steady centre the sort of calm that still has an opinion. It suits a chimney breast, the gap between two windows, or a bedroom wall above the headboard. Pair it with pale linen, light timber and brushed steel, and let one mid-blue cushion or throw echo the darker band. Don’t crowd it with busy pattern or heavy gold; the crane needs space either side to read properly. On fine-art paper the flat blues stay smooth and even.
