The floor finish is the reference
Judge Moth Wing against your actual wood finish, not a generic wood species label. The starting material direction here is ivory seating and dark walnut. Moth Wing has considerably more depth than Mushroom SW-9587, making it a distinct darker beige-gray direction.
Ivory seating creates contrast across the room, while walnut needs its own close boundary check against the wall.
Test the dominant wood color, not one grain line
Check the outline between Moth Wing and the darkest part of the floor or wood furniture. Deep paint and dark timber may lose separation in evening light. Decide whether that continuous dark effect is intended, or whether a lighter painted boundary would give the room clearer structure.
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.
The condition for keeping Moth Wing
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 trim color comparison covers that related choice.
Keep the Moth Wing 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.
