Marble Quarry

This is the kind of yellow undertone that works in more rooms than it does not, which is rarer than it sounds. Vista Paint files it as 8425.

Light reflectance measures 39.0, which is enough to keep a room bright without bouncing light around. Chroma 8.2 sits in a comfortable middle: present enough to notice, restrained enough to live with.

Bedrooms and living rooms, where it is seen in lamplight as much as daylight. South light flatters it. In a north-facing room it can turn cold, so sample that wall first. For a secondary wall, Dunn-Edwards Lighthouse gives a natural step up in brightness without feeling like a mismatch (roughly 51.3 LRV points apart).

Depending on the bulb, this can genuinely read as yellow or as orange - it sits right on the border between the two, only 11° apart. Rooms already built around blues and cool greys are the hardest fit for this color - the two are opposites, and opposites next to each other rarely feel calm.

Next to it, white trim reads brighter and cooler than it does anywhere else in the house - the gap in light reflectance is what does that, not the trim paint itself. For layering, pair this with a clearly lighter mid-tone on a secondary wall or cabinetry, and keep the ceiling close to white. The gap between each step should be big enough to see without thinking about it (roughly 39.0 / 62 / 85 on the reflectance scale).

For anyone tied to a different brand, Sherwin-Williams Escape Gray (SW 6185) is the nearest stand-in, at a delta-E of 1.34. This is not a rare shade: 4 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 39 percent of the Vista Paint range. This is a crowded part of the scale - 540 colors measure within a point of 39.0 - so most brands will have something close. Vista Paint lists it in the K codes, alongside 1,318 other colors.
