Smoky Blue and Debonair: the documented difference
Smoky Blue has an LRV of 15; Sherwin-Williams Debonair SW-9139 is 34. The difference is 19 points, with Debonair returning more light under the reference measurement. Choose by the material relationship as well as the number. Smoky Blue's low LRV gives its gray-softened blue architectural weight rather than a pale wash effect. Debonair is a cool blue softened by slate gray.

The choice beside cognac leather and white trim
Cognac leather provides a warm colored counterpoint; extra blue accessories are optional because the wall already carries a strong direction.
Set up both candidates with cognac leather and white trim. Use equal-sized boards with the intended finishes and place them in the same orientation. Do not put one directly beside a window and leave the other in shadow. A difference that follows the position rather than the board is a lighting observation, not evidence that the formula changed.
What the comparison can—and cannot—settle
The alternative Slate Tile has an LRV of 15. The undertones and neighboring colors covers that related choice.
Look at the sample from the entry as well as close up; a deep wall is judged across the room. Assess Smoky Blue and Debonair alone as well as side by side. The unchosen board will not remain in the finished room, and a preference created only by that neighbor may not survive its removal. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
