Which should you pick

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

Pick Eggplant (BM 1379) for a small room or a north-facing room, because it is 3.9 LRV points lighter (10.8 vs 6.9), so it bounces back more of the limited light
Pick Plum (Behr S-H-670) for a south-facing room, because its Lab b* is -12.6 against -7.5, so it is the cooler of the two and offsets warm direct sun
Pick Eggplant (BM 1379) to warm a north-facing room, because it is the warmer of the two (Lab b* -7.5), which counters cool indirect light
