The decision for this particular color
Smoky Blue can be considered for whole house if its color and depth suit the space; the first design question is a blue feature wall with enough light to show the gray. Smoky Blue's low LRV gives its gray-softened blue architectural weight rather than a pale wash effect.
Why the cognac leather and white trim relationship matters
Cognac leather provides a warm colored counterpoint; extra blue accessories are optional because the wall already carries a strong direction.
Smoky Blue and Slate Tile both have a published LRV of 15. That equality describes reflectance, not matching colorants or identical undertones.
Walk the connecting sightlines
Map where Smoky Blue 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
Look at the sample from the entry as well as close up; a deep wall is judged across the room. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Smoky Blue 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.
