Bowling Green

It has enough yellow-green to be read as a color, and enough depth to hold a wall. Vista Paint catalogs it as Bowling Green, 0437.

LRV 20.0 - comfortably in the range that suits a whole room rather than one wall. A chroma of 14.3 is enough to register as a real color choice, without the intensity that would force the rest of a room to match it.

Bedrooms and living rooms, where it is seen in lamplight as much as daylight. This is a color worth testing in the specific room it is going in - cool colors shift more than warm ones do between north and south walls. Behr Such Melodrama makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 34 points apart in light reflectance).

This color sits right on the line between green and yellow - cooler light nudges it toward yellow, warmer light keeps it in green (about 12° apart on the color wheel, for anyone measuring). Rooms already built around purples 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 20.0 / 53 / 85 on the reflectance scale).

Benjamin Moore Nicolson Green (CW-500) runs close enough - delta-E 1.45 - that swapping brands should not change how the room looks. This is not a rare shade: 3 colors from other brands sit within delta-E 2 of it. Matte or low-sheen suits it on walls; higher gloss will exaggerate the undertone.

It is lighter than 18 percent of the Vista Paint range. Vista Paint lists it in the C codes, alongside 1,421 other colors.
