Start with the documented color character
Smoky Blue is a deep blue softened by gray. A physical comparison is needed to decide how that character works with your own finishes. 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. Slate Tile is a muted deep blue-gray. This supplies a named color control; the LRV gap alone does not identify the warmer, greener or pinker paint.
Use Slate Tile as a control
Give Smoky Blue enough illuminated area to reveal its color, then move the same board into the normal shadow. Compare it briefly with Slate Tile. Decide whether the hue is important everywhere or whether a near-black impression is acceptable in the darker parts of the planned surface.
Separate a persistent cast from a comparison effect
Look at the sample from the entry as well as close up; a deep wall is judged across the room. The warm-versus-cool comparison covers that related choice.
If the unwanted cast remains beside a permanent finish under normal light, that is a practical reason to replace Smoky Blue. If it appears only beside an unused sample, remove the comparison and assess the intended palette alone. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
