Green Oxide is a pale, weathered verdigris green — cool and minerally, like oxidised copper or lichen on stone — the sort of colour that wants natural materials and honest, slightly aged companions around it. Don't fight that character with anything too clean and plasticky.
Start with your off-white. Farrow & Ball Au Lait (LRV 80) is the obvious choice — a warm, milky neutral that keeps things soft and lets Green Oxide do the talking on woodwork, ceilings or an adjacent wall. If you want something a touch more architectural, Paint & Paper Library Paper III (LRV 75.3) is another lovely creamy option that reads light without going stark. Either of these keeps the scheme breathing.
For depth and grounding, go to Mylands Cigar BH.20 (LRV 11.8). That rich, smoky tobacco brown is gorgeous as a contrast on a fireplace, internal joinery or even a piece of furniture — it gives Green Oxide's cool mineral quality something earthy to push against and stops the scheme feeling flat. This is your anchor.
Want a little drama? Dulux Fuchsia Falls 2 (LRV 29.8) is the wildcard. A bright, cool magenta-pink sits opposite green on the wheel, so a small dose — a chair, a cushion, the inside of a cupboard — gives you a knowing pop without overwhelming the calm. Keep it as an accent, not a co-star.
Now the bit people always ask: what about metals and wood? This is where Green Oxide really sings. Aged or antique brass brings a deliberate note of warmth against the cool green — far better than bright chrome, which just disappears into it. And oak, walnut, natural stone and unbleached linen all reinforce that organic feel. Skip cool grey-toned floors; they'll make the green look slightly sour.
Practical advice: in a north-facing room Green Oxide reads greyer and more mineral — lean on the warm Au Lait to balance it. In south light it lifts and reads softer and more sage. Always test a decent-sized board on more than one wall before you commit, and check it morning and evening.
