Beauvais No.195 is one of those warm, characterful Mylands tones that falls apart if you fight it with anything cool or clinical. The job is to lean into its warmth, not dilute it.
Start with the woodwork. Never brilliant white next to Beauvais — it'll look harsh and make the wall colour go muddy. Reach for a soft chalky white instead. Paper III from Paint & Paper Library (LRV 75.3) or Au Lait by Farrow & Ball (LRV 80) both do the job nicely — light enough to frame the room, warm enough to sit in the same family. Au Lait in particular has that creamy, milky softness that flatters earthy walls.
For accents, think putty and ochre. A warm mid-tone keeps the scheme grounded without going flat. And here's where it gets interesting — Beauvais loves a bit of depth alongside it. Cigar BH.20 from Mylands (LRV 11.8) is a gorgeous deep brown-oxblood that works as a feature wall, a fireplace, or joinery in an adjoining space. It reads rich and considered, not heavy.
If you want a proper punch of personality, a deep dusky pink-red like Dulux Fuchsia Falls 2 (LRV 29.8) brings real life when used sparingly — a single chimney breast or an alcove. It's bolder than it sounds on paper, so test it.
The metal matters too. Aged or antique brass is the right note here — unlacquered if you can get it. Chrome and bright nickel will look cold and out of place. Same goes for hardware, light fittings and picture frames.
And the classic "but what about" — yes, olive green works a treat. A deep, muted olive on adjoining joinery or a runner brings out the earthiness without competing.
Practical advice: paint big test patches and live with them across a full day. Beauvais shifts noticeably between morning and lamplight, and you want the whole scheme tested under the light you actually live in.
