The decision for this particular color
Moth Wing can be considered for whole house if its color and depth suit the space; the first design question is a grounded wall behind lighter furniture. Moth Wing has considerably more depth than Mushroom SW-9587, making it a distinct darker beige-gray direction.
Why the ivory seating and dark walnut relationship matters
Ivory seating creates contrast across the room, while walnut needs its own close boundary check against the wall.
Moth Wing has an LRV of 29; Sherwin-Williams Mushroom SW-9587 is 57. The difference is 28 points, with Mushroom returning more light under the reference measurement.
Walk the connecting sightlines
Map where Moth Wing begins and ends before repeating it through the house. A deep room can work as an intentional enclosure while a passage needs another treatment. Check adjoining doorways with the ordinary lights on, preserving readable edges and a coherent route between rooms.
A shared palette does not require one paint everywhere
Check the dark wood against the wall; if both lose their outlines, add a lighter break or select less depth. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Moth Wing 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.
