Blue 07 is one of those proper deep, brooding navies that does its best work when you commit to it. Don't fight it with cool contrast — drench it. Walls, woodwork and ceiling all in the same colour, then let lamplight and texture do the heavy lifting. Half-measures with a dark blue like this just look unfinished.
The key to keeping it from going funereal is warmth. Cool greys and crisp whites will leave it cold and a bit dead. Instead, lean into warm metals — aged brass, antique copper, bronze — and aged timbers. A walnut or oak floor under Blue 07 is cracking.
For specific pairings:
- Mylands Cigar BH.20 (LRV 11.8) is your earthy, smoky brown — perfect for a leather sofa moment or a piece of joinery that grounds the scheme without breaking the moodiness.
- Dulux Copper Glow (LRV 30.1) brings that essential metallic warmth as an accent — think a feature alcove, the inside of a cabinet, or carried through in soft furnishings.
- Paint & Paper Library Sand I (LRV 95.4) or Farrow & Ball All White (LRV 92) for the relief — use one on a ceiling if you don't want to fully drench, or on adjoining woodwork to lift the scheme and give the eye somewhere to rest.
The one rule I'd hold you to: introduce a single ochre or oxblood textile — a cushion, a throw, a rug. That hit of warm earth tone is what stops the whole thing reading as gloomy and tips it into atmospheric instead.
Practical tip — Blue 07 in a north-facing room with poor light can go flat, so this is a scheme for evenings and lamplight, not a bright family kitchen. Get your sample up, live with it after dark, and make sure your bulbs are warm white (2700K), not cool daylight. That's where this colour comes alive.
