Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Tidewater (SW 6477) for a small room or a north-facing room, because it is 6 LRV points lighter (65 vs 59), so it bounces back more of the limited light
- Pick Tidewater (SW 6477) for a south-facing room, because its Lab b* is -0.3 against 2.7, so it is the cooler of the two and offsets warm direct sun
- Pick Rainwashed (SW 6211) to warm a north-facing room, because it is the warmer of the two (Lab b* 2.7), which counters cool indirect light
