Understanding west light
A west-facing room gets no direct sun before early afternoon. In the morning its light is indirect, soft and slightly cool — close to that of a north-facing room. Then the sun swings round, comes through the window lower and lower, and its colour passes from white to golden, then to orange at sunset. A wall colour is therefore seen under two opposite lights in the same day, and that is what must be tested: a sample pot looked at at 10 am and at 6 pm.
The colours that love both
The warm neutrals — Onslow No.48, Clerkenwell No.21, Hoxton Grey No.72 — are the safest: calm in the morning, golden at night, never too much. The earths and taupes — Egerton Place No.297, Amber Grey No.156, London Brick BH.07 — go further into evening warmth without shouting, because they hold grey. The muted pinks and reds — Peach Flesh Pink No.268, Huguenot No.49 — amplify the sunset: a choice for those who live in their living room at night.
The colours to handle with care
Proper yellows turn orange under the setting sun: prefer a golden beige such as Wharf Sacking No.127. Pale blues and cool greys are handsome in the morning and dull at night, when the golden light muddies them; if you want fresh, take a greyed green such as Serpentine No.192, which holds both. We detail all this in how light affects colour.
