Onyx White vs Opal

Onyx White and Opal come from the same Benjamin Moore collection. Hue-wise, Onyx White belongs to the beige-white family and Opal to the beige family. The 8-point LRV gap — 84 for Opal vs 77 for Onyx White — means Opal will open up a space more effectively. Both share a red character, which means they'll respond to light and surrounding materials in similar ways. ΔE 4.7 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
