Follow the room through its ordinary day
Judge Upward under the light you actually use, rather than expecting one constant screen appearance. Its LRV is 57; the key concern is an everyday blue for a bright room and its shaded corners . Upward's denim-blue and gray character gives a clear color direction at a light-to-medium depth.
Why the white linen and pale oak relationship matters
Pale oak and white linen can keep the room restrained, but the adjoining shaded area still needs to support the same blue impression.
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.
Keep the surroundings in the test
Track which part of Upward feels most prominent in each condition: the main hue, its grayed quality or its depth. Keep white linen and pale oak 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 in the room's weaker light before adding it to an open hall. The undertones and neighboring colors covers that related choice. The physical-sample checklist covers that related choice.
Record the condition that made Upward 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.
