Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Sea Salt (SW 6204) for a small room or a north-facing room, because it is 2.6 LRV points lighter (63 vs 60.4), so it bounces back more of the limited light
- Pick Palladian Blue (BM HC-144) for a south-facing room, because its Lab b* is 2.1 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
