Stonington Gray is a cool, blue-grey with a sneaky violet undertone — and that undertone is the thing you have to plan around. Get it wrong and the whole scheme tips muddy; get it right and it's one of the most elegant greys Benjamin Moore makes.
Whites first. Always pair Stonington Gray with a crisp, cool white on woodwork and ceilings. Farrow & Ball All White (LRV 92) is exactly the right call here — it's a clean, undertone-free white that keeps the trim sharp. Avoid warm whites at all costs. Anything with a yellow or cream base will expose the violet in the grey and leave your skirting looking faintly jaundiced.
For depth and contrast, reach for a soft ink-blue. Paint & Paper Library Blue Blood (LRV 16.4) is a cracking partner on a feature wall, an island, or panelling — deep enough to anchor the scheme without going cold. If you want a richer, more unexpected accent, Dulux Fuchsia Falls 2 (LRV 29.8) plays nicely with that violet undertone in cushions, a chair, or a single bold door.
For a softer, lighter layer — say a connecting hallway or a quieter room next door — Mylands Beehive Place No.140 (LRV 58.6) gives you a warmer mid-tone that bridges Stonington Gray to the rest of the house without fighting it.
Keep your metals cool: brushed nickel, stainless, or matte black ironmongery. Brass and warm bronze will clash with the blue-violet base.
The "but what about warmth?" question always comes up — and the answer is texture, not colour. Bring warmth through pale linen, cool stone, and grey-toned timber rather than reaching for a warm beige that'll muddy the grey.
Practical tip: paint a decent-sized board and stand it against your trim white before committing. North-facing rooms will pull the violet forward; south light tames it right down.
