By PRN Michael Colour is the decision people agonise over and get wrong for a predictable reason: they choose from a small card under shop lighting, then apply it to a north-facing British room in November. The paint is rarely the problem. The light is.
This guide covers how to choose colour for the light you actually have, how to build a palette that works across a whole home, and the practical testing that prevents expensive mistakes.
Light Comes Before Colour
The same paint reads completely differently depending on which way a room faces. This matters more in the UK than in sunnier climates because our light is often flat and grey.
| Aspect | Light quality | Generally works |
|---|---|---|
| North-facing | Cool, indirect, constant | Warmer tones; avoid stark white, which reads grey and cold |
| South-facing | Warm and bright for much of the day | Almost anything; cooler tones are balanced by the light |
| East-facing | Bright mornings, flatter afternoons | Tones that work in both, tested at two times of day |
| West-facing | Cooler mornings, warm evenings | Colours that take a warm cast well |
| Little natural light | Artificial light dominates | Either a warm pale tone or a deliberately deep enveloping colour |
Counterintuitively, a dark room is often better served by a deep colour than a pale one. Pale paint in a dim room reads muddy; a deep tone reads intentional and can feel warmer.
Building a Whole-Home Palette
Deciding each room separately produces a house that feels disjointed, particularly where rooms are visible from one another or open onto a hallway.
- Choose one connecting colour for the hallway and landing, which is what ties the house together.
- Pick two or three neutrals that will recur throughout — a wall neutral, a woodwork tone, and one more.
- Allow each room one distinct colour drawn from a related family rather than an unrelated one.
- Keep woodwork consistent across the house, or at least across each floor. Constantly changing skirting colour is visually noisy.
- Check adjoining rooms together. Stand in the doorway and look at both.
- Use an existing item as the anchor — a rug, a painting, a sofa you are keeping.
Undertones, Which Explain Most Mistakes
Two greys can look identical on a card and clash on a wall, because one has a blue undertone and the other a green or violet one. Undertone is why a “grey” reads lilac in your hallway.
Practical test: place the colour next to a piece of plain white paper. The undertone becomes visible immediately. Do the same with the colours you plan to use together, and with any fixed elements you are keeping, such as floor tiles or a worktop.
Whites deserve the same attention. There are warm whites, cool whites and white with a hint of almost anything, and the wrong white beside a warm floor looks like a mistake rather than a choice.
Test Properly, Which Almost Nobody Does
- Buy sample pots and paint a large patch — at least A3, ideally bigger. A small dab tells you almost nothing.
- Paint onto lining paper or card rather than the wall, so you can move it around the room.
- Look at it at three times of day: morning, afternoon and under artificial light in the evening.
- Move it to different walls, because the same colour reads differently opposite a window and beside it.
- Two coats, since one coat rarely shows the true colour.
- Check it against your fixed elements — flooring, worktops, tiles, sofa.
- Check under your actual bulbs. A 2700K bulb and a 4000K bulb make a colour look like two different paints.
Finishes and Practical Choices
Finish affects both durability and how colour reads. Matt absorbs light and hides wall imperfections but marks more easily; eggshell and satin are more washable and reflect more light; gloss is hard-wearing and shows every underlying flaw.
Practical guidance: durable washable finishes in hallways, kitchens, bathrooms and children’s rooms; matt where you want depth and the wall sees little traffic; and moisture-resistant formulations in bathrooms and kitchens, where standard emulsion fails.
Check what is on the wall already. Painting over old gloss, distemper or heavily patched plaster needs appropriate preparation and sometimes a specialist primer. And in older properties be alert to asbestos in textured coatings such as artex — do not sand suspect surfaces without testing.
UK Housing Stock and Local Considerations
In the North West, housing and property coverage appears in the Manchester Chronicle and Liverpool Tribune, both with extensive Victorian terraced stock. Yorkshire housing is followed by Leeds Angle, Sheffield Voice and Bradford Daily.
Scotland, where tenement flats and a separate building standards and warrant system apply, is covered by Glasgow Bulletin and Edinburgh Scope. Northern Ireland, with its own regulations, is reported by the Belfast Record.
Midlands housing, trades and retail appear in Birmingham Focus, Coventry Insight, Leicester Echo, Derby Digest and Nottingham Times. The Newcastle Brief and Hull Report cover the North East and Humber.
Southern and coastal housing, with its own damp and exposure considerations, is covered by Brighton Update, Southampton Ledger, Plymouth Wire and Bristol Outlook. London flats and conversions are reported by London Signals and Capital Outlook. Housing and energy support policy is followed via DWP UK Latest News, with construction and property trade reporting in Trade Mirror.
Frequently Asked Questions
Should I paint a small dark room white?
Not necessarily. Pale colours in a dim room often read grey and flat. A deeper warm tone can feel considerably better, particularly in a room used mainly in the evening.
How many colours should a house have?
Two or three neutrals plus one accent per room, all drawn from related families. A connecting hallway colour ties it together.
Can I paint over wallpaper?
Sometimes, if it is sound and well adhered, though seams and pattern may show through and removal is generally better. Test a small area first.
Why does my grey look purple?
Undertone. Many greys have a violet or blue base that becomes obvious in certain light. Compare against plain white paper before buying.

The Bottom Line
Start with the light rather than the colour. North-facing rooms need warmth, and a dark room often suits a deep tone better than a pale one.
Build a whole-home palette around a connecting hallway colour and two or three recurring neutrals. Check undertones against plain white paper. And test with large patches on movable card, at three times of day, under your actual bulbs, before buying a single tin.
