Hill and Vale

There is nothing quiet about this one - it is meant to be noticed. Hill and Vale is Vista Paint's AC156.

Chroma 31.9 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 14.0 puts it in the middle of the scale, but saturation, not lightness, is what you will react to.

If the room already has pinks and warm blush tones 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.

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. 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 14.0, 50 and 85 on the light-reflectance scale, for reference).

For a secondary wall, Sherwin-Williams Beguiling Mauve gives a natural step up in brightness without feeling like a mismatch (roughly 25.6 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.

Across the other brands, nothing lands within delta-E 2 of this one - there is no easy substitute.

It is lighter than 11 percent of the Vista Paint range. This is a crowded part of the scale - 310 colors measure within a point of 14.0 - so most brands will have something close. Vista Paint lists it in the K codes, alongside 1,318 other colors.
