What 6 tells you about Sealskin
The published LRV of Sherwin-Williams Sealskin SW-7675 is 6. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Sealskin gives a very deep warm-brown alternative to black, a distinct choice even when shadows reduce the visible difference.
The choice beside cream plaster and oak doors
Oak doors and cream plaster create a useful frame for the brown, with the door edge checked under the least favorable light.
Draw the proposed dark area on a room photograph and compare it with a broad physical Sealskin sample in shadow. The LRV describes the starting depth, while the size and location of that area determine its role. Check whether adjacent dark furniture remains legible.
What the comparison can—and cannot—settle
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. Sealskin is a deep warm brown. The value measures reflectance, so it cannot by itself identify an undertone, a coating finish or the amount of illumination needed in the room. The daylight and evening-light checks covers that related choice.
Choose the brown deliberately and compare the door edge in low light before painting all the trim. Do not read LRV 6 as a percentage improvement in perceived room brightness. Make the decision with the board upright at the actual wall or cabinet position, including the least illuminated portion. The north-facing room assessment covers that related choice. Before ordering samples, compare room-planning features in the paint color visualizer roundup.
