Choose the edge before choosing the white
The best trim for Marshmallow depends on the fixed whites and the amount of contrast you want. Compare a close boundary with a clearer outline before selecting a named white. 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.
Put the trim sample in its real orientation
Place two trim candidates as narrow strips beside Marshmallow, with the fixed cabinet white still visible. Review from the doorway so the strips read as architecture rather than isolated paint. A small difference is acceptable when intentional, but three unresolved whites can make the palette harder to read.
The manufacturer's coordinating suggestions include Anew Gray SW7030 and Foothills SW7514. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—pink-beige marble and oak—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
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.
Approve both intended finishes beside Marshmallow. The same color on trim and wall can still show a boundary because the surfaces reflect light differently; a single flat paint chip cannot settle that finish decision. The LRV and depth guide covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
