The decision for this particular color
Acier can be considered for whole house if its color and depth suit the space; the first design question is gray millwork that carries more weight than the walls. Acier is deeper than Dorian Gray and lighter than Felted Wool, giving a practical intermediate gray-depth comparison.
Why the cream walls and stainless steel relationship matters
Stainless steel is reflective and changes with the surroundings; a medium-gray cabinet needs to work with it rather than imitate it.
Acier has an LRV of 32; Sherwin-Williams Dorian Gray SW-7017 is 39. The difference is 7 points, with Dorian Gray returning more light under the reference measurement.
Walk the connecting sightlines
Carry one Acier 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 cream walls and stainless steel 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
Review the cabinet face under its actual light so medium gray does not become an unexpectedly dark mass. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Acier 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.
