Holland Park No.5 is one of those quiet, warm Mylands tones that does its best work wrapping a whole room — walls, ceiling and trim in soft tonal variation rather than fighting against a hard contrast. Treat it as an envelope, not a feature.
The single most important rule: don't pair it with brilliant white woodwork. A cold, optical-bright white will throw Holland Park's warmth into relief and make it read cream and, frankly, a bit grubby. Instead, take the woodwork a notch deeper into warm stone or putty territory. Mylands Artichoke BH.13 (LRV 27.6) is a lovely partner here — a muted, slightly green-grey putty that grounds the scheme without going dark or contrasty. It gives you that lived-in, tonal layering rather than a stark frame.
For a broader, airier feel, Paint & Paper Library Slate IV (LRV 67.5) works as a soft, light companion — useful on a ceiling or in an adjoining space to keep things feeling open while staying in the same gentle, dusty family.
When you want a proper anchor — a chimney breast, a piece of joinery, a low panel — reach for something genuinely deep. Dulux Sapphire Springs 1 (LRV 6.4) brings a rich, inky depth that lets Holland Park's warmth glow against it. That's your full tonal range sorted: light, mid putty, and a dark accent.
Beyond paint, layer in natural materials — old oak, aged brass, linen, unbleached wools. Holland Park sits beautifully alongside warm timber and looks far richer than it does on a chip.
Practical advice: paint a big sample board, at least A2, and live with it for a couple of days. North-facing rooms will pull Holland Park cooler and quieter; south light will warm it considerably. And whatever you do, sample your trim colour against it before committing — that's where these schemes are won or lost.
