Choose the edge before choosing the white
The best trim for Rosemary 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. Rosemary is deep enough that pairing it with black counters creates a question about the outline between two dark planes.
Pale wood stools add room-level contrast, but the countertop-to-cabinet join still needs to remain intentional under working lights.
Put the trim sample in its real orientation
Decide whether trim should outline Rosemary sharply or sit within the dark painted area. Test a light strip and a closer-value strip on the actual casing shape. This is a choice about architectural emphasis: bright outlines highlight every opening, while a quieter boundary changes the room silhouette.
The manufacturer's coordinating suggestions include Ethereal White SW6182, Oyster White SW7637 and Deep Forest Brown SW9175. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—black counters and pale wood stools—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
The condition for keeping Rosemary
Retain a visible boundary between the two dark surfaces or introduce a lighter separating surface. The coordinating color options covers that related choice.
Approve both intended finishes beside Rosemary. 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.
