The floor finish is the reference
Judge Porpoise against your actual wood finish, not a generic wood species label. The starting material direction here is cream limestone and walnut shelving. Porpoise is lighter than Urbane Bronze while remaining a deep gray-bronze option.
Cream limestone can define the built-in as a whole, whereas walnut shelves need a closer check against the painted interior surfaces.
Test the dominant wood color, not one grain line
Check the outline between Porpoise and the darkest part of the floor or wood furniture. Deep paint and dark timber may lose separation in evening light. Decide whether that continuous dark effect is intended, or whether a lighter painted boundary would give the room clearer structure.
Porpoise has an LRV of 13; Sherwin-Williams Urbane Bronze SW-7048 is 8. The difference is 5 points, with Porpoise returning more light under the reference measurement.
The condition for keeping Porpoise
Check the outline of the shelving against the dark paint; keep depth where it clarifies the architecture. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep the Porpoise board vertical at the floor edge. A match to one pale grain line can misrepresent the dominant color across the installed floor. Judge the broad timber background from standing height. If the floor will be refinished, repeat the comparison with the approved new stain sample before ordering the wall paint. The coordinating color options covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
