Tapestry Green is one of those proper warm sages with a grey-green depth to it, and the rule with a colour like this is simple: never fight the warmth. Brilliant white on the woodwork will make it look cold and a bit municipal. Instead, anchor it with a soft off-white.
Au Lait (LRV 80) from Farrow & Ball is a lovely creamy choice for trim and ceilings — it's got enough warmth to sit happily next to the sage without going yellow. If you want something a touch cleaner but still soft, Paper III from Paint & Paper Library (LRV 75.3) does the same job with a slightly cooler, more paper-white feel. Either is a far better call than a stark white.
For contrast and richness, this is where Tapestry Green really comes alive. Cigar BH.20 from Mylands (LRV 11.8) is a deep tobacco brown that grounds the scheme beautifully — think a chunky leather sofa or a dark joinery accent. And for a bit of unexpected life, Fuchsia Falls 2 from Dulux (LRV 29.8) brings the dusty rose / pink energy that flatters sage so well in cushions, a chair, or a feature piece. Layer in terracotta and ochre through textiles and you've got a genuinely warm, lived-in room.
The big "but what about" here is metal. Don't let anyone talk you into chrome or polished nickel — cool metals deaden this colour stone dead. Old oak and unlacquered brass are what you want; they pull the warmth straight out of the sage and make the whole thing glow.
Practical advice: Tapestry Green shifts noticeably between daylight and lamplight, so get a tester on the wall and live with it for a couple of days. In a north-facing room it'll lean greyer and cooler, which is exactly why the warm off-white trim matters so much — it does the heavy lifting to keep things feeling cosy rather than cold.
