Lavender Quartz

Saturated enough that everything else in the room answers to it. Vista Paint files it as 1170.

Chroma 26.0 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.

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. LRV 33.0 puts it in the middle of the scale, but saturation, not lightness, is what you will react to.

If the room already has greens in the floor, a rug, or the furniture, this color will fight it rather than sit well beside it - the two sit at opposite ends of the color spectrum, which is exactly why they clash instead of blend.

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. A natural scheme here moves in three clear steps: this color on the main wall, a noticeably lighter mid-tone for a second wall or built-in, and a near-white on the ceiling. Each jump should be obvious at a glance, not something you have to squint to tell apart (roughly 33.0, 59 and 85 on the light-reflectance scale, for reference).

For a secondary wall, Dunn-Edwards Lighthouse gives a natural step up in brightness without feeling like a mismatch (roughly 57.3 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, PPG Mauve Magic (1180-5) is the closest equivalent at delta-E 2.01, 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 32 percent of the Vista Paint range. The name is not unique: Valspar 4001-9C also sells a color called Lavender Quartz, and it is not the same shade. Vista Paint lists it in the C codes, alongside 1,421 other colors.
