Warm grey or cool grey: how to choose?

There is no such thing as a neutral grey. Every grey leans — towards yellow, pink or brown on one side, towards blue, green or violet on the other. That lean, the undertone, is what makes one grey feel cosy in a room and icy in the next.

Here are twelve Mylands greys, six warm and six cool, compared so you know which to choose before opening the tin.

Warm grey or cool grey: how to choose?

The short answer

Choose a warm grey — The Boltons No.28, Frieze No.84, Ludgate Circus No.89 — for a north- or east-facing room, or a scheme of timber and natural materials. Choose a cool grey — Sloane Square No.92, Islington No.23, Mid Wedgwood No.113 — for a contemporary scheme of white, black and metal, or to cool a very sunny room.

01

Warm grey · the palest

The Boltons™ No.28

  • Grey
  • Pale tone
  • West light
  • LRV ≈ 66%

A very pale grey with a pink-brown undertone, almost a light greige. It is the easiest warm grey in the range: it brightens like an off-white and warms like a beige, without being either. The grey for a north-facing bedroom or living room that wants to stay light.

Our tip — North-facing rooms, bedrooms, bright living rooms

Frieze — Bathroom
02

Warm grey · the stone grey

Frieze™ No.84

  • Grey
  • Pale tone
  • South light
  • LRV ≈ 65%

A pale grey with a beige undertone, the colour of limestone. It is the grey we recommend most often for skirtings and woodwork beneath a deep colour — it does a white's job without a white's hardness — and it is just as handsome across whole walls. Impossible to go wrong with it.

Our tip — Woodwork beneath a deep colour, hallway walls, ceilings

Home office setup with a wooden desk, chair, lamp, and wall-mounted grid organiser, room painted in pale neutral colour
03

Warm grey · the light taupe grey

Ludgate Circus™ No.89

  • Grey
  • Pale tone
  • North light
  • LRV ≈ 53%

A pale-to-mid grey with a yellow-brown undertone, stronger than Frieze. It has the quality of old plaster greys: it looks as if it had always been there. In a living room of wood and leather furniture, it makes a ground that warms everything placed against it.

Our tip — Living rooms, dining rooms, schemes of wood and leather

Warm grey living room with classical decor, including a chandelier, fireplace, and various sculptures.
04

Warm grey · the ochre grey

Grey Ochre™ No.152

  • Grey
  • Pale tone
  • North light
  • LRV ≈ 52%

The name says it: a grey that carries ochre. Its yellow undertone is the most pronounced of the warm greys on this list, which makes it precious in a truly cold room — a hallway, a utility room, a north-facing bedroom — where it gives the impression of a sunbeam on a grey wall.

Our tip — Hallways and sunless rooms, rustic kitchens

View the colour → Already in your basket (limit 1 per order)
Grey bathroom with a sink, mirror, and shower area.
05

Warm grey · the thatch grey

Chambers Gate™ No.85

  • Grey
  • Pale tone
  • North light
  • LRV ≈ 50%

A mid grey with a beige-yellow undertone, a touch deeper than Grey Ochre, with the softness of old thatch. It is a country grey, at ease with beams, stone and linen — and one of the few mid greys that never look sad on an overcast day.

Our tip — Country houses, beamed rooms, dining rooms

Cotton Street — hallway
06

Warm grey · the deepest

Amber Grey™ No.156

  • Grey
  • Mid tone
  • West light
  • LRV ≈ 26%

A mid-deep grey whose amber undertone — golden brown — pulls it towards taupe. It is the most enveloping warm grey on the list, the grey of a study or an evening living room. Under lamps it turns the colour of blond tobacco; by day it stays a grey, but a grey with blood in it.

Our tip — Studies, libraries, evening living rooms

Maugham White — hallway
07

Cool grey · the palest

Sloane Square™ No.92

  • Grey
  • Pale tone
  • North light
  • LRV ≈ 68%

A very pale, almost perfectly neutral grey — a whisper of yellow, no more — which reads as cool beside The Boltons. It is the grey of contemporary interiors: clean, calm, without texture. It makes an ideal ground for art and design furniture, and it keeps its crispness in every light, north included.

Our tip — Contemporary interiors, galleries, bright rooms

Islington — Bathroom
08

Cool grey · the bluish grey

Islington™ No.23

  • Grey
  • Pale tone
  • North light
  • LRV ≈ 61%

A pale grey with a very slight blue-green undertone, the colour of a January sky. It cools a warm room — a south-facing kitchen, a west-facing bedroom — and gives the whites around it a porcelain gleam. Facing north it keeps its clarity but loses its softness: pair it then with warm materials, timber and brass.

Our tip — South-facing kitchens, west-facing bedrooms, bathrooms

Mid Wedgwood — Diningroom
09

Cool grey · the grey-blue

Mid Wedgwood™ No.113

  • Grey
  • Pale tone
  • North light
  • South light
  • LRV ≈ 46%

The bluest grey on this list — a Wedgwood porcelain grey, with a candid blue undertone. It is an elegant, slightly formal grey, that of Georgian dining rooms and entrance halls. It asks for light and cool whites; with a cream white it looks dull.

Our tip — Dining rooms, entrance halls, classical woodwork

Classic grey kitchen with white walls, black appliances, and a central island.

Cool grey · the mid grey

Drury Lane™ No.115

  • Grey
  • Mid tone
  • North light
  • LRV ≈ 24%

A mid grey that is almost neutral, with just enough blue to stay on the cool side. It is the 'architect's grey' par excellence: it draws volumes without colouring them, and shows off concrete, metal and dark timber. It stays crisp all day, facing north or south.

Our tip — Lofts, studies, contemporary kitchens

Modern bedroom with green walls, a bed with white pillows, and a black pendant light.
11

Cool grey · the slate grey

Oratory™ No.237

  • Grey
  • Dark tone
  • North light
  • LRV ≈ 14%

A deep grey with a blue undertone, the colour of dry slate. It has the depth of a night blue without being one, which makes it very easy to live with colour-drenched — walls, woodwork and ceiling — in a study or bedroom, even a north-facing one. Superb with brass and walnut.

Our tip — Colour drenching, studies, bedrooms

Cool grey · the deepest

Leadenhall™ No.118

  • Grey
  • Mid tone
  • North light
  • LRV ≈ 18%

A mid-deep grey of rare neutrality — neither blue, brown nor green — which reads as cool simply because it warms nothing. It is the grey of exterior joinery and graphic kitchens, the one that makes a red door or white tiles stand out. Use it as an accent rather than on four walls.

Our tip — Exterior joinery, kitchen cabinets, accents

How to tell a warm grey from a cool one

Put the sample beside a sheet of white paper in daylight. A warm grey looks faintly beige, pink or yellow; a cool grey looks faintly blue, green or violet. On our colour card, the warm greys on this page — The Boltons No.28, Frieze No.84, Ludgate Circus No.89, Grey Ochre No.152, Chambers Gate No.85, Amber Grey No.156 — all carry an undertone between yellow and pink. The cool greys — Sloane Square No.92, Islington No.23, Mid Wedgwood No.113, Drury Lane No.115, Oratory No.237, Leadenhall No.118 — lean towards blue, or towards nothing at all.

Three questions to decide

Which orientation? North and east light is cold: a cool grey looks cooler still there — crisp if you want freshness, sad if you want comfort — while a warm grey simply stays grey. South and west light is warm: a cool grey stays crisp there, a warm grey can turn beige. Our guide How light changes colour takes each case in turn.

Which materials? Wood, leather, linen, terracotta and brass call for a warm grey. Concrete, steel, white marble, black and chrome call for a cool one. Mixing the two can be done — but then the grey must follow the dominant material.

Which white beside it? A warm grey with a warm white (Holland Park No.5, Maugham White No.2); a cool grey with a cool white (Pure White No.1, Charterhouse No.4). Crossing them makes the grey look dirty and the white look yellow. See also our greys for a bedroom, our grey schemes and all our greys.

Frequently asked questions

How can I tell whether a grey is warm or cool?
Put the sample beside a sheet of white paper in daylight: a warm grey looks beige, pink or yellow; a cool grey looks blue, green or violet. The undertone is invisible alone, obvious by comparison.
Which grey for a north-facing room?
For a comfortable room, a warm grey: The Boltons No.28 for a light room, Ludgate Circus No.89 or Grey Ochre No.152 for more substance. A cool grey such as Sloane Square No.92 stays crisp there, but more austere.
Which grey for a south-facing room?
A cool grey stays crisp in warm south light: Sloane Square No.92 for pale, Drury Lane No.115 for mid, Oratory No.237 for deep.
Which white to pair with a grey?
A white of the same temperament: warm with a warm grey (Holland Park No.5), cool with a cool grey (Pure White No.1). Crossing them makes the grey look dirty.
