The floor finish is the reference
Judge Debonair against your actual wood finish, not a generic wood species label. The starting material direction here is cream walls and brushed brass. Debonair occupies a middle ground between pale slate blues and near-black navies.
Cream walls allow blue millwork to become the architectural color, with brass used as a smaller highlight rather than the main contrast.
Test the dominant wood color, not one grain line
Use the broad background of the timber to assess Debonair, rather than matching one grain streak. Wood contributes color as well as texture. Decide whether the paint should contrast with that warmth or repeat it, keeping the dominant fabric in the same view.
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.
The condition for keeping Debonair
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 trim color comparison covers that related choice.
Keep the Debonair board vertical at the floor edge. A match to one pale grain line can misrepresent the dominant color across the installed floor. Judge the broad timber background from standing height. If the floor will be refinished, repeat the comparison with the approved new stain sample before ordering the wall paint. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
