Vigilant

Neutral enough to sit under other colors, with a yellow cast underneath. Vista Paint files it as 0563.

Chroma 6.4 means the color content is small, which is exactly why the yellow cast matters so much - there is nothing else here to distract from it. The yellow cast leans into warm light rather than fighting it, so this is a forgiving choice under standard incandescent or warm-LED bulbs.

At this LRV (21.0), a room reads as neither bright-white nor dim - a genuinely middle-of-the-road amount of light comes back off the wall. Suits both quiet, restful rooms and busier shared spaces, which is most of what makes a neutral a neutral.

For a secondary wall, Kilz Brushed Metal gives a natural step up in brightness without feeling like a mismatch (roughly 41 LRV points apart).

Behr Smoky Trout (MQ2-53) matches it closely enough that no one will tell them apart on a wall. 3 other-brand colors land within delta-E 2 of this one - a well-populated part of the spectrum with several near-equivalents to choose from. Eggshell is a common middle ground here - enough durability for a lived-in room without the sheen that would draw attention to wall imperfections.

It is lighter than 19 percent of the Vista Paint range. Among grays it is one of the strongest: only 1 percent of them carry more colour. Vista Paint lists it in the C codes, alongside 1,421 other colors.
