Which should you pick
Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.
- Pick Outerspace (SW 6251) for a small room or a north-facing room, because it is 6 LRV points lighter (12 vs 6), so it bounces back more of the limited light
- Pick Outerspace (SW 6251) for a south-facing room, because its Lab b* is -5.1 against -3.5, so it is the cooler of the two and offsets warm direct sun
- Pick Cyberspace (SW 7076) to warm a north-facing room, because it is the warmer of the two (Lab b* -3.5), which counters cool indirect light
