Farrow & Ball Ammonite No. 274 - An Architect's Honest Review
Farrow & Ball Ammonite No. 274 is the lightest of the brand's Relaxed Neutrals, and it is the one most often dismissed as a simple pale grey. Named after the fossils found along the Dorset coast, it sits on an unusually fine line: Farrow & Ball describes it as neither too warm nor too cool, while many independent sources read a slight warm greige lean in it. I have specified Ammonite in period terraces and pared-back new builds alike, and the pattern is consistent - it behaves as a quiet backdrop when the room supports it and goes flat the moment the room stops.
The core tension is that Ammonite is balanced rather than decisive. At an LRV of roughly 66-69 it is light without being white, and its balanced soft grey character means it takes on the temperature of whatever surrounds it. Warm oak and lamplight pull it gently warm; cool north daylight and cold LEDs pull it towards a pale, lifeless stone grey. If you want a neutral that announces its undertone, Ammonite is not that colour. If you want one that adapts and recedes, it is one of the most useful in the Farrow & Ball range.
This review sets out Ammonite's undertone and LRV, how it behaves in each orientation and under artificial light, which trims, floors and metals suit it, and who should and should not choose it. I have also been open about where published figures conflict, because the numbers for this colour vary more than they should.
Ammonite No. 274 - The Key Facts
Collection | Farrow & Ball Relaxed Neutrals - the lightest of the group |
LRV | ~66-69 (light zone - open and airy without reading as white; published figures vary by source) |
Undertone | Balanced soft grey with a faint warm lean - Farrow & Ball calls it neither too warm nor too cool |
Character | Calm, understated, stone-like - suits period homes and pared-back modern interiors |
Best trim | Wevet No. 273 (Farrow & Ball's complementary white) |
Best orientation | South or west-facing - warm daylight keeps the grey soft rather than flat |
Main risk | Reads as a flat, characterless pale grey in north-facing rooms under cool LEDs, where nothing warm is present to give it depth |
Ammonite Undertones - What Is Actually Going On
Ammonite's undertone is a balanced soft grey - and the sources do not fully agree on which way it leans. Farrow & Ball positions it as neither too warm nor too cool, and describes it as calm and clear. Most independent colour databases class it as a warm grey or greige, and one describes it as a pale grey-green. These are descriptions of the same thing from different angles: a grey with a small measure of warmth in the mix and no strong hue pulling it anywhere.
In practice, that means Ammonite has no obvious flag. It does not drift pink, yellow or green on a wall the way more committed neutrals can. The warmth shows mainly beside cool surfaces such as steel, glass and cold stone, and the grey shows mainly beside cream paint or warm timber, so its character depends heavily on what is placed next to it. I treat it as a colour whose result is decided by the room, not by the tin.
That restraint is also why its nearest neighbours are so easily confused with it. For how the two closest pale neutrals in the range separate from each other - one a chalky off-white, the other a warmer stone-toned off-white - the Slipper Satin vs Skimming Stone guide is the cleanest side-by-side, and it is a useful calibration before you commit to Ammonite.
LRV - What 66-69 Means in a Real Room
At an LRV of roughly 66-69, Ammonite is a light colour with real body - it lifts a room noticeably, yet it reads as a considered wall colour rather than a near-white. A note on the numbers: three of the sources I cross-checked cluster between 66 and 69, while one outlier reports 56. I have used the 66-69 range and I would treat any single figure for this colour as indicative rather than exact, which is one more reason to sample it in your own room.
Set against its neighbours, Ammonite is roughly 6-9 points lighter than Cornforth White at about 60, and roughly 6-9 points deeper than Slipper Satin at about 74-75. Against Skimming Stone, which sources place at about 67-69, the difference is inside the margin of error. For the mid-tone neighbour that Farrow & Ball places just below Ammonite, the Cornforth White review explains where the extra depth earns its place.
In a room with decent daylight, this LRV keeps walls feeling spacious without the glare of a bright white. In a small north-facing room it gives less lift than a lighter neutral, and the gap to a true white trim such as Wevet, at roughly 82-84, is wide enough that the trim will look markedly crisper than the walls. That contrast is usually a benefit, but it needs to be planned for rather than discovered.
How Ammonite Behaves in Different Light
South-Facing Rooms
South-facing rooms are where Ammonite is easiest to live with. Strong, warm daylight supplies the faint warmth the colour needs, so the grey stays soft rather than cold. Across a day it moves from a pale stone in the morning to a slightly creamier grey by late afternoon, and the change is gentle rather than dramatic. In very bright rooms, direct midday sun can wash it lighter than the sample suggested, so judge it in the shade of the room as well as in the sun.
North-Facing Rooms
North-facing rooms are where Ammonite loses its edge. The cool, indirect light removes the faint warmth from the mix, and what remains is a flat, pale grey with the character of unpainted plaster. The fix is rarely a deeper paint. It is warmth supplied by everything else in the room: 2700K lamps, timber, wool and linen, and at least one warm metal. If the room is also small and dark, a deeper neighbour such as Cornforth White will often look more deliberate than Ammonite looks washed out.
East and West-Facing Rooms
East-facing rooms give Ammonite a clear, slightly warm morning and a flatter afternoon. Once the sun moves round, the room loses its warm light and the colour settles towards a neutral grey, which suits a bedroom or breakfast room used mainly early in the day. West-facing rooms are kinder to it in the evening, when low golden light warms the grey into something close to soft stone. For a sitting room used after work, that late shift is one of the colour's quiet strengths.
Artificial Lighting
Artificial light changes Ammonite more than daylight does, because the colour has so little undertone to resist it. At 2700K the grey warms and softens, and the room feels settled in the evening. At 3000K it is still comfortable, though a little more neutral. At 4000K and above it turns pale, cool and slightly clinical, and no amount of good furniture rescues it. I put dimmable warm-white fittings in every room where Ammonite is specified.

Trim Colours and What to Pair With Ammonite
Trim - Soft Whites, Not Stark Ones
Wevet No. 273 is the trim I specify first - it is Farrow & Ball's own complementary white for Ammonite, and at an LRV of roughly 82-84 it gives a clear step up in lightness without a harsh edge. The full logic for this white is in the Farrow & Ball Wevet review. Where the brief is tonal and low-contrast, Slipper Satin is a softer alternative, and the Farrow & Ball Slipper Satin review covers how its chalky off-white behaves on joinery. I would avoid brilliant, blue-leaning whites on trim, because they make Ammonite look dull by comparison.
Floor Materials
Natural oak, limed oak and pale ash are the most reliable floors beside Ammonite. Their light, slightly warm tone sits comfortably against a balanced grey and keeps the room from feeling cold. Honed limestone and soft-toned encaustic tile also work well, because they share the stone quality of the paint. Orange-toned or red-toned timber is harder, since the strong warmth makes the wall look greyer than it is.
Metal Finishes
Aged brass, unlacquered brass and bronze are the most flattering metals for Ammonite. Their warmth gives a balanced grey the depth it cannot supply itself, and they age well in period rooms. Blackened iron works for a sharper, more architectural result. Polished chrome can feel cold against this colour, so I use it only where the brief is clearly contemporary and the room has plenty of natural light.
Accent Colours
Ammonite takes deep, inky colours very well. A dark navy, a deep bottle green or a soft charcoal on joinery or a single feature wall gives the scheme a spine that the pale walls cannot provide alone. For a tonal route, Purbeck Stone - the deepest of the Relaxed Neutrals - keeps the palette quiet and cohesive. Pinks and peaches are harder to place, because they push Ammonite towards a cold grey by contrast.
Ammonite Room by Room
Bathrooms
Bathrooms suit Ammonite when natural light is good and the palette carries some warmth. My usual scheme is Ammonite walls, Wevet ceiling and trim, a limestone or oak-toned floor, aged brass taps, and white or off-white sanitaryware. Specify a finish suited to damp rooms, and keep lamp temperatures warm so the walls do not turn clinical at night. In a windowless bathroom I would choose a lighter or warmer colour instead.
Bedrooms
Ammonite makes a restful bedroom colour because it is quiet and does not compete with the bed. In south and west-facing bedrooms it reads soft and settled, particularly with linen bedding, oak furniture and 2700K bedside lamps. In north-facing bedrooms I would pair it with warm textiles and timber and sample very carefully first. The room is used at night, so the artificial light is the light that counts.
Living Rooms
Living rooms are where Ammonite is most versatile. It suits a period room with cornicing and panelled joinery, and it suits a modern open-plan space with minimal detail. It works best when the room has layers of warm material - rugs, timber, brass lamps, aged leather - because those supply the warmth that the paint deliberately leaves out. If you are torn between Ammonite and a warmer stone-toned neutral, the Farrow & Ball Skimming Stone review is the right comparison to read.
Kitchens
Ammonite works on kitchen walls when the cabinetry and worktops are doing the talking. Against painted shaker cabinets in a deeper tone, or timber and stone worktops, it provides a calm, pale surround that reflects daylight well. I would be more cautious on cabinets themselves, where its restraint can read as unfinished in a dim room. Under-cabinet lighting should be warm white, since cool strips will strip the colour of character.
Home Offices and Studies
Ammonite is a calm, low-distraction choice for a home office or study. The balanced grey does not tire the eye over a long working day, and it keeps a small room feeling open. I pair it with a dark joinery feature, a timber desk and a warm task lamp so the room has some depth. In a north-facing study, add warmth deliberately or the walls will read as institutional.
Who Ammonite Is Right For - And Who It Is Not
Ammonite is right for you if:
You want a quiet, adaptable neutral that supports the room rather than leading it - Ammonite's balanced grey recedes behind furniture, art and timber. It gives a calm backdrop that suits both period and contemporary interiors, and it rarely fights with what is placed in front of it.
The room is south or west-facing, or has good daylight at some point in the day - warm natural light supplies the faint warmth that stops the grey from going flat. In those conditions Ammonite looks soft and settled, with a stone-like depth that a plain pale grey does not have.
Your interior already carries warm materials - oak floors, brass or bronze fittings, linen and wool textiles all give Ammonite the warmth it deliberately leaves out. The result is balanced and layered rather than cold.
You are happy to plan the lighting properly - warm-white bulbs at 2700K, ideally on dimmers, make a measurable difference to how this colour reads in the evening. If you are prepared to specify that, Ammonite performs well in almost every room.
Ammonite is not right for you if:
The room is north-facing, small and dark, and you do not plan to add warmth - without warm daylight or warm materials, Ammonite reads as a flat pale grey. A deeper neighbour such as Cornforth White, or a warmer off-white, is usually a better fit for that situation.
You want an obvious, defined warm neutral - Ammonite is balanced, not warm. If the brief is cosy, creamy or inviting from the first glance, a warmer stone-toned colour will deliver that more directly.
You rely on cool LED lighting throughout - at 4000K and above the colour turns pale and clinical. Changing the colour will not fix a lighting specification that works against it.
You are not prepared to sample in the actual room - the LRV and undertone figures for this colour vary between sources, and its nearest neighbours are very close. A large sample, viewed in your own light, is the only reliable way to be sure.
How Ammonite Compares to Similar Colours
vs Skimming Stone No. 241 - Skimming Stone sits at almost the same LRV - about 67-69 against Ammonite's 66-69 - so the difference is not about brightness. Skimming Stone reads as a warmer, more stone-toned off-white, while Ammonite is the more grey of the two. Choose Skimming Stone for a gentle cream warmth, and Ammonite where you want a more restrained, calmer result. The Farrow & Ball Skimming Stone review covers its behaviour in detail.
vs Cornforth White No. 228 - Cornforth White is the mid tone of the Relaxed Neutrals, at an LRV of about 60 - roughly 6-9 points deeper than Ammonite. Farrow & Ball also describes it as neither too warm nor too cool, so the family resemblance is genuine, and Cornforth simply carries more body. It suits rooms where Ammonite would look washed out, while Ammonite suits rooms that want more lift.
vs Slipper Satin No. 2004 - Slipper Satin is a chalky off-white with a gentle warm cast, at an LRV of about 74-75, roughly 6-9 points lighter than Ammonite. Some sources give higher figures for it, so treat that number as approximate. It reads as the brighter, cleaner choice, while Ammonite reads as the more definite grey.
vs Wevet No. 273 - Wevet is a white rather than a neutral, at an LRV of roughly 82-84, so it sits some 13-18 points lighter than Ammonite. It is Farrow & Ball's complementary white for Ammonite, which makes it the natural trim, ceiling and joinery partner rather than a wall alternative. Use Ammonite for walls and Wevet for the architecture around them.
Frequently Asked Questions
Is Ammonite warm or cool?
Ammonite is balanced, with a faint warm lean. Farrow & Ball describes it as neither too warm nor too cool, and most independent sources read it as a warm grey or greige. In practice it takes its temperature from the room: warm light and warm materials make it gently warm, and cool north light makes it cooler and flatter. That adaptability is the reason it is useful, and the reason it needs sampling.
Is Ammonite grey or beige?
Ammonite reads as a soft grey with a hint of warmth rather than as a beige. Beside cream paint or warm timber the grey is obvious, and beside cold surfaces the warmth becomes visible. It does not read strongly beige in the way a warmer stone neutral can, so if you want a clearly beige result, look at Skimming Stone instead.
What is the best trim colour for Ammonite?
Wevet No. 273 is the best trim for Ammonite. It is Farrow & Ball's own complementary white for the colour, and it creates a soft but clear step up in lightness. Slipper Satin is a gentler, lower-contrast alternative for a tonal scheme. I would avoid brilliant, blue-leaning whites, which can make Ammonite look dull.
Does Ammonite work in a north-facing room?
It can, but it needs help. The cool daylight removes the faint warmth from the colour, and it can read as a flat pale grey. Warm 2700K lighting, timber, warm metals and soft textiles make a real difference, and a deeper neighbour such as Cornforth White may suit the room better. Whichever you choose, sample at large scale and judge it in the evening as well as by day.
How is Ammonite different from Skimming Stone?
The two are almost identical in lightness and differ mainly in temperature. Their LRVs sit within a point or two of each other, so neither makes a room brighter. Skimming Stone is the warmer, more stone-toned of the pair, and Ammonite is the greyer and more restrained. Put both on the wall side by side before deciding, since the difference is subtle and shows most in changing light.
The Verdict
Farrow & Ball Ammonite is a quietly capable neutral - in a room that gives it something to work with. It is not a showy colour, and it does not carry a strong undertone. It is a balanced grey that supports good light, warm materials and careful lighting, and rewards them with a calm, stone-like finish.
In the right room - south or west-facing, with warm timber and warm lamps - it is one of the most restful and adaptable wall colours I know. In a dark, cool room without those supports, it is merely pale. Published LRV figures also vary, so I would not rely on any one number. For how Ammonite compares to the warmer, creamier neighbour that most people weigh it against, the Farrow & Ball Skimming Stone review is the useful next read.
Test it in this order: First, paint two large boards, at least A2 in size, and fix them to different walls, with one beside your trim colour. Second, view them at 8am, at midday and at dusk, noting when the colour looks flat or cold. Third, switch on your actual 2700K evening lighting and check the boards after dark. Fourth, hold a piece of your floor material and your metal finish against the board. If it still looks calm and settled in every one of those four checks, Ammonite will hold up on the wall.
