Which should you pick

Rules of thumb computed from the LRV and Lab values in the table above; no room test was done.

  • Pick Green Onyx (SW 9128) for a small room or a north-facing room, because it is 1 LRV points lighter (31 vs 30), so it bounces back more of the limited light
  • Pick Evergreen Fog (SW 9130) for a south-facing room, because its Lab b* is 6.6 against 12.4, so it is the cooler of the two and offsets warm direct sun
  • Pick Green Onyx (SW 9128) to warm a north-facing room, because it is the warmer of the two (Lab b* 12.4), which counters cool indirect light
