From the trade
Paint Purbeck Stone and your chosen match on two boards in the same finish. A flat and an eggshell in one colour never look identical.
Check them on the darkest wall in the morning and again under your own lamps at night. That is where small differences show.
Give the merchant the brand, colour name and code shown here. It avoids the guesswork of a scanned match.
In your light
Pick the way your window faces and the time of day. The same paint can look like three different colours.
North light is steady but cool and grey. It pulls blues and greys colder and makes greens look heavier. Warm based colours hold up best.
An approximation of how light colour and strength shift a paint. Use it to narrow a shortlist, then paint a sample board and look at it at these same times.
Building a scheme
Worked out from undertone and depth, the way a decorator would put a scheme together. Paint samples side by side before you commit.
A pale colour from the same undertone as Purbeck Stone, so the ceiling does not look stark white against it.
One step lighter or darker on skirtings, doors and window boards. A tonal scheme is the easiest way to make a room feel finished.
A dark colour that sits under it. Use on a fireplace wall, an inside door, a kitchen island or a hall below the dado.
Purbeck Stone is close to neutral, so almost any colour will sit beside it. These have enough character to show.
Colour values are on screen approximations taken from published community colour libraries (Farrow & Ball; Farrow & Ball (cross check); Little Greene; Benjamin Moore; Sherwin-Williams, Valspar, PPG, Behr, Dunn-Edwards), compiled 2026-10-09. Scores use CIEDE2000. Screens, light and sheen all change how paint looks, so always check a physical sample.
