What 7 tells you about Rock Bottom
The published LRV of Sherwin-Williams Rock Bottom SW-7062 is 7. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Rock Bottom approaches black in reflectance, making a very dark green-gray effect central to the scheme.
The choice beside warm brick and cream trim
Warm brick and cream trim can define the facade or interior feature even when the mossy color is difficult to distinguish in shade.
Draw the proposed dark area on a room photograph and compare it with a broad physical Rock Bottom 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
Rock Bottom has an LRV of 7; Sherwin-Williams Night Owl SW-7061 is 13. The difference is 6 points, with Night Owl returning more light under the reference measurement. Rock Bottom is a very dark cool green-gray with a mossy quality. 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.
Judge the sample in shade first; the mossy green should be a bonus, not a requirement that fails at night. Do not read LRV 7 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.
