Nocturnal Gray vs Blue grey
Nocturnal Gray (Benjamin Moore) and Blue grey (RAL Classic) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. The 3-point LRV gap — 16 for Blue grey vs 14 for Nocturnal Gray — means Blue grey will open up a space more effectively. A ΔE of 1.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Nocturnal Gray vs Blue grey in Real Spaces
2 real rooms side by side. Nocturnal Gray and Blue grey 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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
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. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

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