Nocturnal Gray vs Onyx
Nocturnal Gray and Onyx come from the same Benjamin Moore collection. Nocturnal Gray reads as blue-grey, while Onyx reads as grey — two distinct hue families, not close cousins. The 9-point LRV gap — 14 for Nocturnal Gray vs 5 for Onyx — means Nocturnal Gray will open up a space more effectively. Where Nocturnal Gray leans blue, Onyx reads red — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 21.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nocturnal Gray vs Onyx in Real Spaces
3 real rooms side by side. Seeing Nocturnal Gray and Onyx in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Nocturnal Gray reflects noticeably more light off the walls, making the space read more open than Onyx.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Nocturnal Gray reflects noticeably more light off the walls, making the space read more open than Onyx.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Nocturnal Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Nocturnal Gray vs Onyx Simulated Comparison
5 simulated room previews — drag the slider on each to see Nocturnal Gray on one side and Onyx 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.
