Candle Wax

It has enough yellow undertone to be read as a color, and enough depth to hold a wall. 0374, from Vista Paint.

16.0 on the light-reflectance scale puts it in the middle third, which is the part of the scale with the fewest surprises. A chroma of 13.0 is enough to register as a real color choice, without the intensity that would force the rest of a room to match it.

Works as a whole-room color in spaces that are lived in rather than passed through, where its depth has time to register. South light flatters it. In a north-facing room it can turn cold, so sample that wall first. Dunn-Edwards Silver Bullet makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 30.5 points apart in light reflectance).

In warm light this stays yellow; under cooler, daylight-style bulbs it can slide toward orange. It's close enough to that edge that a sample is worth checking in the room's own lighting, not under a store's. 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.

The lighter the trim beside this, the more it will seem to glow - a side effect of the light-reflectance gap rather than anything special about the trim color. 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 16.0 / 51 / 85 on the reflectance scale).

PPG Positively Palm (1030-6) runs close enough - delta-E 1.73 - that swapping brands should not change how the room looks. This is a relatively uncrowded spot in the spectrum - just 2 colors from other brands come this close. Matte holds the color truest; a subtle sheen will lift it half a shade under lamps.

It is lighter than 14 percent of the Vista Paint range. Vista Paint lists it in the C codes, alongside 1,421 other colors.
