The floor finish is the reference
Judge Marshmallow against your actual wood finish, not a generic wood species label. The starting material direction here is pink-beige marble and oak. Marshmallow's pink undertone gives the white a specific relationship to investigate beside pink-beige stone.
Marble veining can be flattering while the slab background disagrees, so the entire stone sample should remain visible.
Test the dominant wood color, not one grain line
View Marshmallow 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.
Marshmallow has an LRV of 82; Sherwin-Williams Ivory Lace SW-7013 is 79. The difference is 3 points, with Marshmallow returning more light under the reference measurement.
The condition for keeping Marshmallow
Use the marble's plain background as well as its veining in the test; pink should connect rather than dominate.
Keep, compare or change direction
Keep the Marshmallow 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.
