Little Greene is a genuinely British outfit — family-owned, independent, and manufacturing its paint here in England. That's not marketing fluff bolted onto an imported product; the company has roots going back to a paint works established in the 1700s, and they've kept production on home soil. If buying British matters to you, Little Greene is one of the safe bets alongside Farrow & Ball, Mylands and Edward Bulmer.
A couple of things worth knowing beyond the "made in England" line. Little Greene works in partnership with the National Trust and English Heritage, which is where a lot of their period-accurate colours come from — archive shades pulled from historic properties and reissued. So when you're picking something like Air Force Blue or the deep, characterful Hollyhock, you're often buying into a documented heritage palette, not just a fashionable name.
They're also strong on green — 48 greens in the FiniSpec library, which is a serious spread — plus a deep bench of neutrals and blues. The collection runs the full range, from near-white through to inky darks, so you can build a whole scheme within the one brand and keep the undertones talking to each other. Mister David, a warm, slightly murky green, is a good example of the kind of nuanced colour they do well.
The "but what about" question is usually about finishes and durability. Little Greene's water-based finishes are low-VOC and genuinely good — their Intelligent Matt Emulsion is wipeable and tougher than a standard matt, which makes it sensible for hallways and kids' rooms. Their oil-based eggshell for trim is excellent but slower to dry and yellows slightly over years, so for woodwork I'd lean toward their Intelligent Eggshell unless you specifically want the oil.
Practical advice: order Little Greene sample pots and paint a decent A4 patch — their pigment-rich colours shift a lot between daylight and lamplight, so judge them on the actual wall before you commit.
