Onyx vs Night Jewels 1
Onyx (Benjamin Moore) and Night Jewels 1 (Dulux) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 5 vs 5 — so neither will read significantly brighter or darker than the other. Where Onyx leans red, Night Jewels 1 reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.2 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Onyx vs Night Jewels 1 in Real Spaces
1 real room side by side. Onyx and Night Jewels 1 are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. The distinction reads clearly at room scale, making the choice between them concrete.

Onyx vs Night Jewels 1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Onyx on one side and Night Jewels 1 on the other.
Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
