6th May 2026 - Why Your Walls Look Wrong in May
If your walls suddenly look wrong this week, it's not your imagination.
May light is brutal — and it's exposing every paint decision you made in January.
Something happens to UK homes in the first week of May that designers know and clients usually don't.
The sun climbs higher. The days stretch past 8pm. North-facing rooms start receiving bounced light they haven't seen since September. South-facing rooms get blasted with a directness they were spared all winter. And the colours you chose under a low December sun and warm bulbs suddenly read completely differently.
Whites turn yellow. Greys turn lilac. That moody green you fell in love with in February looks oddly flat. The wood floor you swore was warm oak now reads orange.
This is normal.
Three things to do before you reach for the roller:
1. Live with it for two more weeks.
Your eye is recalibrating! So is the light. By late May, the sun's angle settles and you'll see your rooms more truthfully. Most "I hate it now" panic resolves itself by half-term.
2. Look at the room at three times of day, not one.
Morning, mid-afternoon, and dusk under lamp light. A colour that fails at 11am can be the reason the room sings at 7pm — and a north-facing snug should be specced for evening, not noon. When do you actually use that room? That’s a deciding factor on changing the colour...or not.
3. If you do repaint, test on the wall it's going on, not the wall opposite.
Paint behaves entirely differently on a sunlit wall vs the wall facing it. A2-sized sample on each elevation. Lived with for a full week. Non-negotiable.
The deeper point:
Specifying paint for a UK home means specifying for four seasons of light, not one. The colours that hold up year-round are rarely the ones that look best on the swatch in B&Q under fluorescent strip lighting at 3pm in January.
It's why I push clients toward complex, multi-pigment colours — Farrow & Ball Pavilion Gray, Paint & Paper Library Slate V, Edward Bulmer Jonquil — over flat, single-pigment shades. They shift with the light instead of fighting it.
If your walls have started looking wrong this week, the answer is almost never "repaint." It's "wait, look properly, then decide."
Save this for the May panic. It happens every year.
