Which should you pick

Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.

Pick Lullaby (SW 9136) for a small room or a north-facing room, because it is 2 LRV points lighter (65 vs 63), so it bounces back more of the limited light
Pick Lullaby (SW 9136) for a south-facing room, because its Lab b* is -1.1 against 3.4, so it is the cooler of the two and offsets warm direct sun
Pick Sea Salt (SW 6204) to warm a north-facing room, because it is the warmer of the two (Lab b* 3.4), which counters cool indirect light
