Mellow Blue

The kind of neutral that changes name depending on the light, though the green cast underneath it stays put. 0468, from Vista Paint.

Chroma 4.8 is the whole difference: below four a color reads as grey, above ten the green cast takes over. Warm bulbs will soften it; daylight bulbs push it further cool.

76.0 on the light-reflectance scale puts it in the middle third, which is the part of the scale with the fewest surprises. It is the sort of color that goes on every wall of a house without feeling overwhelming.

Dunn-Edwards Lighthouse makes a good second wall color here - different enough to read as a real choice, close enough to still feel related (about 14.3 points apart in light reflectance).

If the brand is not fixed, Behr Mountain Peak White (N430-1) is the same color by measurement - delta-E 0.45. 6 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. A satin finish is worth it in a room that needs to be wiped down often, at the cost of showing a bit more of the wall's surface than a flat finish would.

It is lighter than 80 percent of the Vista Paint range. The name is not unique: Dutch Boy DCP-0468 also sells a color called Mellow Blue, and it is not the same shade. Vista Paint lists it in the C codes, alongside 1,421 other colors.
