Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Porpoise (SW 7047) for a small room or a north-facing room, because it is 5 LRV points lighter (13 vs 8), so it bounces back more of the limited light
- Pick Urbane Bronze (SW 7048) for a south-facing room, because its Lab b* is 4.1 against 6.1, so it is the cooler of the two and offsets warm direct sun
- Pick Porpoise (SW 7047) to warm a north-facing room, because it is the warmer of the two (Lab b* 6.1), which counters cool indirect light
