The floor finish is the reference
Judge Sea Serpent against your actual wood finish, not a generic wood species label. The starting material direction here is white shelves and cognac leather. Sea Serpent's very low reflectance supports a dark navy backdrop, with a black-like appearance possible in weak illumination.
Cognac leather and white shelving can keep the room legible, even when the darkest painted areas show little obvious blue.
Test the dominant wood color, not one grain line
Check the outline between Sea Serpent 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.
Sea Serpent has an LRV of 7; Sherwin-Williams Cyberspace SW-7076 is 6. The difference is 1 points, with Sea Serpent returning more light under the reference measurement.
The condition for keeping Sea Serpent
Plan for a nearly black appearance in weak light and check whether the shelf edges remain readable. The undertones and neighboring colors covers that related choice. The trim color comparison covers that related choice.
Keep the Sea Serpent 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.
