Hannover Hills

A mid-weight yellow undertone. Vista Paint catalogs it as Hannover Hills, 0228.

LRV 13.0 - comfortably in the range that suits a whole room rather than one wall. A chroma of 11.4 is enough to register as a real color choice, without the intensity that would force the rest of a room to match it.

It has enough weight for a main wall and enough restraint for a hallway. It holds up in a north-facing room, which is where warmth is usually missing. PPG Silver Charm makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 32 points apart in light reflectance).

If the room already has blues and cool greys 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 13.0, 49 and 85 on the light-reflectance scale, for reference).

Benjamin Moore Cabin Fever (1540) runs close enough - delta-E 1.37 - that swapping brands should not change how the room looks. This is not a rare shade: 5 colors from other brands sit within delta-E 2 of it. Matte or low-sheen suits it on walls; higher gloss will exaggerate the undertone.

It is lighter than 10 percent of the Vista Paint range. Vista Paint lists it in the C codes, alongside 1,421 other colors.
