Edward Bulmer's Lilac Pink is a gentle, slightly mauve pink, and the single most important decision you'll make is the woodwork. Go with a soft warm white rather than a stark, brilliant cool white. A cold white sitting next to it exposes the mauve undertone and makes the pink look grey and tired — a warm white lets it bloom and stay pretty.
From there, build with depth. Lilac Pink is soft enough that it wants something to anchor it, and three directions all work beautifully.
For a fresh, slightly unexpected pairing, Dulux Almost Pistachio (LRV 80.3) is lovely. That soft green is the natural complement to a mauve-pink — think old-fashioned sweet-pea garden — and at such a high LRV it keeps everything light and airy. Use it on an adjoining wall or in the next room for flow.
If you want drama, reach for deep plummy and inky tones. Paint & Paper Library Blue Blood (LRV 16.4) is a properly rich choice — a dark blue-plum that picks up the mauve in Lilac Pink and gives you a moody, grown-up scheme. Brilliant on a fireplace wall or panelling below the rail.
For warmth and earthiness, Mylands Cigar BH.20 (LRV 11.8) is the one. A deep, smoky brown-plum that grounds the pink and stops it feeling sugary — particularly good in a dining room or snug.
The "but what about" question I always get: *won't pink feel too feminine?* Not if you ground it. Add those deeper plummy or dusty-rose textiles, lean into antique brass rather than chrome or nickel, and the whole room reads sophisticated rather than girly.
Practical tip: paint a big sample board and stand it against your chosen woodwork white before committing. Lilac Pink shifts noticeably depending on the white beside it and the light in the room — north-facing will pull it cooler and greyer, so warm whites earn their keep even harder there.
