Breathtaking Blue

Saturated enough that everything else in the room answers to it. Vista Paint files it as 7327.

Chroma 33.8 is high enough to dominate a room's palette rather than join it. Best reserved for rooms you pass through or visit rather than ones you spend hours in - the intensity that makes a strong first impression can tire the eye over a full day.

South light flatters it. In a north-facing room it can turn cold, so sample that wall first. LRV 32.0 puts it in the middle of the scale, but saturation, not lightness, is what you will react to.

Worth checking before committing to a full wall: oranges and warm terracotta nearby - in a floor, a rug, a piece of furniture - will read as a clash here, not a complement, since the two colors sit at opposite ends of the spectrum.

Warm metals - brass, aged gold, unlacquered fixtures - gain a contrast against this that they do not have against a lighter wall; it is a common reason people choose a color this deep in the first place. The safest multi-color scheme moves from this dark wall to a noticeably lighter secondary tone, then to a near-white ceiling - three genuinely different depths rather than three shades of the same idea (LRV 32.0, 59 and 85, if you're matching by the numbers).

For a secondary wall, PPG Forever Faithful gives a natural step up in brightness without feeling like a mismatch (roughly 48 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, Dunn-Edwards Marina (DE5857) is the closest equivalent at delta-E 2.83, near enough for most rooms. No other brand has a color within delta-E 2 of this one - a genuinely uncommon shade.

It is lighter than 29 percent of the Vista Paint range. Vista Paint lists it in the K codes, alongside 1,318 other colors.
