Choose the edge before choosing the white
The best trim for Seapearl 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. Seapearl's cool gray undertone separates it from whites selected mainly for creamy warmth.
Brick and limestone create different colored boundaries, so a white that agrees with one still needs to be checked against the other.
Put the trim sample in its real orientation
Place two trim candidates as narrow strips beside Seapearl, 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 Feather Down OC-6, Arctic Shadows 1559 and Sleigh Bells 1480. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—brick and pale limestone—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
The condition for keeping Seapearl
Test against both materials in the same light; a gray undertone can read differently next to each.
Approve both intended finishes beside Seapearl. 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.
