What 4 tells you about Jasper
The published LRV of Sherwin-Williams Jasper SW-6216 is 4. It describes light reflectance; it does not specify an undertone or predict the brightness of your room. Jasper's exceptionally low LRV makes black-like depth central to its use, even though the color is green.
The choice beside white stone and aged brass
White stone supplies a broad light plane, while brass emphasizes details; the green need not be obvious in every shadow to be intentional.
Draw the proposed dark area on a room photograph and compare it with a broad physical Jasper 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
Jasper has an LRV of 4; Sherwin-Williams Ripe Olive SW-6209 is 6. The difference is 2 points, with Ripe Olive returning more light under the reference measurement. Jasper is an exceptionally deep green. The value measures reflectance, so it cannot by itself identify an undertone, a coating finish or the amount of illumination needed in the room.
Make the near-black effect part of the plan, then check whether the green is visible in the room's normal light. Do not read LRV 4 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.
