Japonica

This is a statement first and a wall color second. Vista Paint lists it as Japonica (0983).

At chroma 49.9 it will not sit quietly next to another strong color. Used across a whole room it needs restraint in the decor - furniture and textiles that stay quiet so the wall can carry the color.

It holds up in a north-facing room, which is where warmth is usually missing. 42.0 on the light-reflectance scale is unremarkable on its own; the chroma is what actually drives how this color behaves.

Worth checking before committing to a full wall: blues and cool greys 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 42.0, 64 and 85, if you're matching by the numbers).

If a second wall color is wanted in the same room, Dunn-Edwards Clear Vision keeps the jump obvious rather than muddy (roughly 44 LRV points from this one). A flatter finish keeps this much color from creating harsh reflections.

For anyone tied to a different brand, Sherwin-Williams Adventure Orange (SW 6655) is the nearest stand-in, at a delta-E of 2.18. No other brand has a color within delta-E 2 of this one - a genuinely uncommon shade.

It is lighter than 44 percent of the Vista Paint range. This is a crowded part of the scale - 679 colors measure within a point of 42.0 - so most brands will have something close. Vista Paint lists it in the C codes, alongside 1,421 other colors.
