How to Choose Paint Colours You'll Still Love

Most of us have stood in a freshly painted room thinking 'that's not what it looked like on the chart'. A few simple habits make choosing colour far less of a gamble.

Look at the light first

The single biggest influence on how a colour looks is the light in the room. In the UK, north-facing rooms get cool, bluish light all day, which can make greys look cold and whites look flat. South-facing rooms are bathed in warm light that brightens almost anything. East-facing rooms are bright in the morning and dim later; west-facing rooms are the opposite.

So before falling for a shade online, think about when you actually use the room. A colour that looks perfect on a sunny Saturday afternoon may feel gloomy on a dark Tuesday evening in November.

  • North-facing: warmer neutrals, soft yellows and earthy colours tend to work well
  • South-facing: cooler blues, greens and greys hold up nicely
  • East-facing: colours that look good in morning light and under lamps
  • West-facing: warm evening light flatters most colours

Undertones: the hidden colour in every neutral

Almost no neutral is truly neutral. A white might lean pink, yellow, green or blue. A grey might be warm or cold. Undertones are why a 'simple' white can look wrong next to your kitchen units or flooring.

The easiest way to spot an undertone is to hold the sample next to a sheet of pure white paper, or next to other samples of the same colour family. Differences that are invisible on their own suddenly jump out.

Test properly – on the wall, not the chart

Tiny chips on a colour card are almost useless for judging a whole wall. Buy sample pots, or ask your decorator to bring some, and paint large patches – at least the size of a sheet of A4, ideally bigger. Paint them on more than one wall and look at them in the morning, in the afternoon and under your own lamps at night.

Paint swatches on lining paper or card if you don't want patches on the walls; that way you can move them around the room.

Small rooms and dark rooms

The traditional advice is to paint small rooms white to make them feel bigger. It can work, but in a small room with little light, white often just looks grey and flat. Many designers now suggest the opposite: embrace a deeper colour, and the room feels cosy and deliberate rather than gloomy.

If you'd prefer light colours, choose a warm white or soft neutral rather than a stark brilliant white, and keep the ceiling a shade lighter than the walls.

Making rooms flow together

In most homes you can see from one room into another. Colours don't need to match, but they should feel like they belong in the same house. A simple approach is to pick a palette of three or four related colours and use them in different proportions around the house – a darker shade in one room becomes an accent in the next.

Keeping the same woodwork colour throughout is another easy way to tie different rooms together.

Common questions

Should the ceiling be white?

Not necessarily. White is the default, but a tint of the wall colour or the same colour throughout can look striking. In rooms with low ceilings, a light ceiling usually helps.

Do decorators help with colour choice?

Many are happy to give advice and bring sample pots, and some offer a colour consultation. The final choice is yours, but their experience of how paints behave on walls is useful.

Will a colour look the same in every brand?

Not always. Colour-matching can be close, but sheen and pigments differ between brands. If a colour matters a lot to you, use the original brand or test the match first.
