The floor finish is the reference
Judge Upward against your actual wood finish, not a generic wood species label. The starting material direction here is white linen and pale oak. Upward's denim-blue and gray character gives a clear color direction at a light-to-medium depth.
Pale oak and white linen can keep the room restrained, but the adjoining shaded area still needs to support the same blue impression.
Test the dominant wood color, not one grain line
Use the broad background of the timber to assess Upward, 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.
Upward has an LRV of 57; Sherwin-Williams Stardew SW-9138 is 43. The difference is 14 points, with Upward returning more light under the reference measurement.
The condition for keeping Upward
Review the blue in the room's weaker light before adding it to an open hall. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep the Upward 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.
