Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Palladian Blue (BM HC-144) for a small room or a north-facing room, because it is 4.6 LRV points lighter (60.4 vs 55.8), so it bounces back more of the limited light
- Pick Yarmouth Blue (BM HC-150) for a south-facing room, because its Lab b* is -2.7 against 2.1, so it is the cooler of the two and offsets warm direct sun
- Pick Palladian Blue (BM HC-144) to warm a north-facing room, because it is the warmer of the two (Lab b* 2.1), which counters cool indirect light
