Choose the edge before choosing the white
The best trim for Black Magic 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. Black Magic and Tricorn Black share the same LRV, so a claimed brightness advantage would be unsupported.
Warm plaster and brass provide a reason to compare Black Magic's slight warmth, using authentic samples rather than the numerical tie alone.
Put the trim sample in its real orientation
Decide whether trim should outline Black Magic 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 Snowbound SW7004, Lemon Meringue SW7561 and Anjou Pear SW6381. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—warm white plaster and brass—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
The condition for keeping Black Magic
Test it directly against Tricorn Black; equal LRV does not mean an identical color impression. The coordinating color options covers that related choice. The cabinet color guide covers that related choice.
Approve both intended finishes beside Black Magic. 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.
