Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Drift of Mist (SW 9166) for a small room or a north-facing room, because it is 5.9 LRV points lighter (69 vs 63.1), so it bounces back more of the limited light
- Pick Drift of Mist (SW 9166) for a south-facing room, because its Lab b* is 4.4 against 8.2, so it is the cooler of the two and offsets warm direct sun
- Pick Edgecomb Gray (BM HC-173) to warm a north-facing room, because it is the warmer of the two (Lab b* 8.2), which counters cool indirect light
