The decision for this particular color
Gray Mist can be considered for whole house if its color and depth suit the space; the first design question is just enough wall color beside white trim. Gray Mist occupies the light off-white end of greige, making subtle separation its more plausible purpose.
Why the white doors and pale stone relationship matters
White doors and pale stone may already create a quiet palette; the added wall color should provide a useful, visible relationship.
Gray Mist has an LRV of 72.83; Benjamin Moore Dove Wing OC-18 is 77.52. The difference is 4.69 points, with Dove Wing returning more light under the reference measurement.
Walk the connecting sightlines
Carry one Gray Mist board from the brightest room to the connecting hall and the room with the least useful daylight. Leave each room's fixed whites visible. The white doors and pale stone palette may work in the main space yet fail beside a different upstairs carpet. Inspect both sides of the connecting doorway; a common paint name does not require an identical-looking wall in every exposure.
A shared palette does not require one paint everywhere
Choose it for restrained separation rather than a definite gray wall; test the boundary from across the room. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Gray Mist passes in the main room but fails against another fixed floor, a related color in that space may be more coherent than repeating one formula everywhere. Review both rooms through the connecting doorway. The living-room palette covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
