Emerald Lights

Saturated enough that everything else in the room answers to it. Vista Paint files it as AC155.

Chroma 27.3 is high enough to dominate a room's palette rather than join it. On one wall of an otherwise neutral room, this reads as a deliberate choice rather than an overwhelming one.

South light flatters it. In a north-facing room it can turn cold, so sample that wall first. LRV 13.0 puts it in the middle of the scale, but saturation, not lightness, is what you will react to.

Rooms already built around pinks and warm blush tones are the hardest fit for this color - the two are opposites, and opposites next to each other rarely feel calm.

Wood tones next to this read darker and richer than they do against a paler wall; it is one of the more dependable effects of putting a light-absorbing color next to anything reflective. 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 13.0 / 49 / 85 on the reflectance scale).

For a secondary wall, Sherwin-Williams Mysterious Mauve gives a natural step up in brightness without feeling like a mismatch (roughly 24.1 LRV points apart). If the wall needs to be washable, eggshell is the highest sheen worth considering before the color starts looking artificial under light.

Switching brands, Behr Chopped Chive (S-H-460) is the closest equivalent at delta-E 2.43, near enough for most rooms. Across the other brands, nothing lands within delta-E 2 of this one - there is no easy substitute.

It is lighter than 10 percent of the Vista Paint range. Vista Paint lists it in the K codes, alongside 1,318 other colors.
