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 Serpent (SW 7615) for a small room or a north-facing room, because it is 3 LRV points lighter (7 vs 4), so it bounces back more of the limited light
- Pick Naval (SW 6244) for a south-facing room, because its Lab b* is -11.0 against -7.0, so it is the cooler of the two and offsets warm direct sun
- Pick Sea Serpent (SW 7615) to warm a north-facing room, because it is the warmer of the two (Lab b* -7.0), which counters cool indirect light
