Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Jasper (SW 6216) for a small room or a north-facing room, because it is 0 LRV points lighter (4 vs 4), so it bounces back more of the limited light
- Pick Greenblack (SW 6994) for a south-facing room, because its Lab b* is -0.4 against 2.1, so it is the cooler of the two and offsets warm direct sun
- Pick Jasper (SW 6216) to warm a north-facing room, because it is the warmer of the two (Lab b* 2.1), which counters cool indirect light
