The decision for this particular color
Laguna Blue can be considered for whole house if its color and depth suit the space; the first design question is a coastal blue with more weight than a pastel. Laguna Blue is a deep oceanic color, so a coastal association should not create an expectation of pale, airy walls.
Why the pale oak and white linen relationship matters
White linen and pale oak can provide contrast, while the dark blue carries the principal color in the room.
Laguna Blue has an LRV of 17; Sherwin-Williams Smoky Blue SW-7604 is 15. The difference is 2 points, with Laguna Blue returning more light under the reference measurement.
Walk the connecting sightlines
Map where Laguna 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
Use it where a substantial blue surface is wanted, then check the evening corner before assuming an airy effect. The north-facing room assessment covers that related choice. The situations that call for another color covers that related choice.
If Laguna 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.
