The floor finish is the reference
Judge Sealskin against your actual wood finish, not a generic wood species label. The starting material direction here is cream plaster and oak doors. Sealskin gives a very deep warm-brown alternative to black, a distinct choice even when shadows reduce the visible difference.
Oak doors and cream plaster create a useful frame for the brown, with the door edge checked under the least favorable light.
Test the dominant wood color, not one grain line
Check the outline between Sealskin 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.
Sealskin has an LRV of 6; Sherwin-Williams Black Fox SW-7020 is 7. The difference is 1 points, with Black Fox returning more light under the reference measurement.
The condition for keeping Sealskin
Choose the brown deliberately and compare the door edge in low light before painting all the trim. The undertones and neighboring colors covers that related choice.
Keep the Sealskin 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.
