Choose the edge before choosing the white
The best trim for Cavern Clay 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. Cavern Clay is a red-orange color choice with depth, making the size of the painted area as important as the exact shade.
Terracotta already provides a large orange field; plain linen can interrupt that repetition without introducing another strong hue.
Put the trim sample in its real orientation
Decide whether trim should outline Cavern Clay 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 Creamy SW7012, Slate Violet SW9155 and Ligonier Tan SW7717. These are separate named colors to sample, not interchangeable formulas. For the material direction considered here—terracotta tile and neutral linen—choose which surface each candidate would occupy before deciding that the whole set belongs in the room.
The condition for keeping Cavern Clay
Use a plain pale fabric to break up the warm surfaces, and compare the paint to the tile's dominant color. The coordinating color options covers that related choice. The cabinet color guide covers that related choice.
Approve both intended finishes beside Cavern Clay. 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.
