Zenith

A color with enough presence that "accent" is really the only honest use for it. Vista Paint catalogs it as Zenith, 0647.

A chroma of 24.0 is well into the range where the color affects everything nearby - light fixtures, glossy surfaces, even skin tones under it. In a room with plenty of natural light, this can cover more wall area than it could in a dim one, where the same color reads heavier.

South light flatters it. In a north-facing room it can turn cold, so sample that wall first. Light reflectance reads 20.0, though with this much color in it that number is the smaller half of the story.

If the room already has oranges and warm terracotta 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.

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. 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 20.0, 53 and 85 on the light-reflectance scale, for reference).

Benjamin Moore Cement Gray makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 40 points apart in light reflectance). This is not a color that benefits from shine - the saturation does the work, and a flat finish lets it do that evenly.

Behr Glass Sapphire (PPU14-02) runs close enough - delta-E 2.78 - that swapping brands should not change how the room looks. Across the other brands, nothing lands within delta-E 2 of this one - there is no easy substitute.

It is lighter than 18 percent of the Vista Paint range. Vista Paint lists it in the C codes, alongside 1,421 other colors.
