Cornforth White

It reads as a neutral with a yellow cast. In the Farrow & Ball lineup this is 228.

A chroma of 4.0 is low enough to read as neutral in most light, but the yellow cast still shifts what the eye calls it. It holds up in a north-facing room, which is where warmth is usually missing.

At LRV 60.0 it sits where most rooms want a wall: light enough to feel open, dark enough to have a surface. Suits both quiet, restful rooms and busier shared spaces, which is most of what makes a neutral a neutral.

If a second wall color is wanted in the same room, Dunn-Edwards Lighthouse keeps the jump obvious rather than muddy (roughly 30.3 LRV points from this one).

Behr Ground Fog (BNC-05) matches it closely enough that no one will tell them apart on a wall. This is not a rare shade: 8 colors from other brands sit within delta-E 2 of it. A satin finish is worth it in a room that needs to be wiped down often, at the cost of showing a bit more of the wall's surface than a flat finish would.

It is lighter than 71 percent of the Farrow & Ball range. Farrow & Ball lists it in the 200 series, alongside 73 other colors.
