Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Atrium White (BM OC-145) for a small room or a north-facing room, because it is 3.2 LRV points lighter (85.1 vs 81.9), so it bounces back more of the limited light
- Pick Atrium White (BM OC-145) for a south-facing room, because its Lab b* is 3.7 against 5.6, so it is the cooler of the two and offsets warm direct sun
- Pick Swiss Coffee (BM OC-45) to warm a north-facing room, because it is the warmer of the two (Lab b* 5.6), which counters cool indirect light
