Give this sample a clear job
Sample Sherwin-Williams Debonair SW-9139 beside the fixed finishes, in the intended orientation and under normal room lighting. The trial should settle 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 comparison fair
Keep the Debonair sample broad enough to show its hue, with cream walls and brushed brass beside it. Remove extra paint chips during the final review and restore the belongings that will remain. Approve the color on its own, rather than a preference that depends on an unchosen neighboring sample.
Approve the actual coating and the least favorable view
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 approved dried board with the complete Sherwin-Williams SW-9139 product and finish specification. Follow the actual coating instructions for application, drying and preparation; the color name does not settle those requirements. The daylight and evening-light checks covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
