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 Star (BM 2123-30) for a small room or a north-facing room, because it is 7.9 LRV points lighter (33 vs 25.1), so it bounces back more of the limited light
- Pick Aegean Teal (BM 2136-40) for a south-facing room, because its Lab b* is -4.1 against -2.6, so it is the cooler of the two and offsets warm direct sun
- Pick Sea Star (BM 2123-30) to warm a north-facing room, because it is the warmer of the two (Lab b* -2.6), which counters cool indirect light
