What 14 tells you about Rosemary
The published LRV of Sherwin-Williams Rosemary SW-6187 is 14. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Rosemary is deep enough that pairing it with black counters creates a question about the outline between two dark planes.
The choice beside black counters and pale wood stools
Pale wood stools add room-level contrast, but the countertop-to-cabinet join still needs to remain intentional under working lights.
Draw the proposed dark area on a room photograph and compare it with a broad physical Rosemary 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
Rosemary has an LRV of 14; Sherwin-Williams Pewter Green SW-6208 is 12. The difference is 2 points, with Rosemary returning more light under the reference measurement. Rosemary is a deep green cooled by gray. 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.
Retain a visible boundary between the two dark surfaces or introduce a lighter separating surface. Do not read LRV 14 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.
