Choose the edge before choosing the white
The best trim for Cotton 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. Cotton's high LRV supplies a clear lightness reference, but the available description does not support a precise undertone claim.
Limestone and white upholstery create a close palette in which the actual material boundary should decide the preferred white.
Put the trim sample in its real orientation
Place two trim candidates as narrow strips beside Cotton, 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 Soft Suede SW9577, Canal Street SW9523 and Limestone SW9599. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—limestone and white upholstery—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
The condition for keeping Cotton
Use the actual stone to assess the white; the published data do not justify a universal undertone promise.
Approve both intended finishes beside Cotton. 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. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
