Blessed Blue

This is the kind of teal that works in more rooms than it does not, which is rarer than it sounds. 0667, from Vista Paint.

30.0 on the light-reflectance scale puts it in the middle third, which is the part of the scale with the fewest surprises. A chroma of 17.5 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. The teal is more noticeable under cool, daylight-balanced bulbs than under standard warm ones, which tend to mute it. Sherwin-Williams Spatial White makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 41.9 points apart in light reflectance).

Worth checking before committing to a full wall: reds and brick tones 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.

Next to it, white trim reads brighter and cooler than it does anywhere else in the house - the gap in light reflectance is what does that, not the trim paint itself. 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 30.0, 58 and 85, if you're matching by the numbers).

Switching brands, Behr Voyage (PPU13-07) is the closest equivalent at delta-E 2.71, near enough for most rooms. No other brand has a color within delta-E 2 of this one - a genuinely uncommon shade. Matte or low-sheen suits it on walls; higher gloss will exaggerate the undertone.

It is lighter than 27 percent of the Vista Paint range. This is a crowded part of the scale - 581 colors measure within a point of 30.0 - so most brands will have something close. Vista Paint lists it in the C codes, alongside 1,421 other colors.
