Follow the room through its ordinary day

Why the ivory seating and dark walnut relationship matters
Ivory seating creates contrast across the room, while walnut needs its own close boundary check against the wall.
Moth Wing has an LRV of 29; Sherwin-Williams Mushroom SW-9587 is 57. The difference is 28 points, with Mushroom returning more light under the reference measurement.
Keep the surroundings in the test
For Moth Wing, inspect the darkest painted position with the ordinary lamps alone. Then compare a better-lit part of the same board. Decide whether the low-light silhouette is desirable; buying stronger bulbs solely to reproduce a daylight photograph may change the whole atmosphere of the room.
A lighting result needs a practical decision
Check the dark wood against the wall; if both lose their outlines, add a lighter break or select less depth. The undertones and neighboring colors covers that related choice. The physical-sample checklist covers that related choice.
Record the condition that made Moth Wing 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.
