The floor finish is the reference
Judge White Down against your actual wood finish, not a generic wood species label. The starting material direction here is warm limestone and beige linen. White Down has more color depth than Ivory White, useful when a very light cream fails to frame warm stone.
Limestone's broad background should guide the white choice; isolated veins and small linen samples can otherwise distract from the permanent surface.
Test the dominant wood color, not one grain line
View White Down vertically where it meets the installed timber. The floor can make a light white look warmer by comparison, but that does not establish a universal undertone. Include the existing trim so the wall is approved between both fixed neighbors rather than against wood alone.
White Down has an LRV of 76.69; Benjamin Moore Soft Chamois OC-13 is 77.4. The difference is 0.71 points, with Soft Chamois returning more light under the reference measurement.
The condition for keeping White Down
Use the stone's background color as the reference, then decide whether the trim should be closer or cleaner.
Keep the White Down 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.
