Tea with Florence is a cool blue-green — there's more water than sage in it — and the pairing job is about balance: keep everything cool and the room can turn chilly; add the right warmth and the colour looks considered rather than cold.
Start with the whites, because that's where most schemes go wrong. A soft, warm off-white gives a cool blue-green something to push against. Paint & Paper Library Paper III (LRV 75.3) is gentle and creamy without going yellow — lovely on trim and cornicing. Farrow & Ball Au Lait (LRV 80) is milkier and a touch warmer again, and works beautifully on ceilings above Tea with Florence walls. Either way, that slight warmth stops the blue-green reading clinical. A stark brilliant white would push it colder — fine if you're after a crisp, bathroom-fresh look, but most rooms want the softer route.
For depth, Mylands Cigar BH.20 (LRV 11.8) is a mid tobacco brown that grounds the scheme the way leather and dark timber do — use it on joinery, a fire surround or in the furniture. Brown against blue-green is a quietly brilliant combination.
And for the accent, Dulux Fuchsia Falls 2 (LRV 29.8) is a bright, cool magenta-pink that sits naturally with a cool blue-green — same temperature family, completely different character. A lampshade, a chair, the inside of a bookcase: a little goes a long way.
Materials: limed oak, slate and aged brass all work — the brass adds warmth exactly where the paint stays cool.
Practical tip: two coats on an A3 board, viewed morning and evening and in the room's least-lit spot. Cool blue-greens shift noticeably — greyer on dull days, greener in sun — so make sure you like both versions before you commit.
