Follow the room through its ordinary day
Judge Debonair under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 34; the key concern is blue millwork without the near-black weight of navy . Debonair occupies a middle ground between pale slate blues and near-black navies.
Why the cream walls and brushed brass relationship matters
Cream walls allow blue millwork to become the architectural color, with brass used as a smaller highlight rather than the main contrast.
Debonair has an LRV of 34; Sherwin-Williams Stardew SW-9138 is 43. The difference is 9 points, with Stardew returning more light under the reference measurement.
Keep the surroundings in the test
Track which part of Debonair feels most prominent in each condition: the main hue, its grayed quality or its depth. Keep cream walls and brushed brass in the view. This creates a usable record of the palette instead of a list of apparently different colors produced by phone exposure.
A lighting result needs a practical decision
Review the blue on a vertical panel from across the room; use its medium depth to separate the millwork. The undertones and neighboring colors covers that related choice. The physical-sample checklist covers that related choice.
Record the condition that made Debonair least convincing as well as its best view. If only a short period of daylight works, change the color or the room plan rather than ignoring the hours when the space is occupied. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
