Black grey vs Steely Gray
Black grey (RAL Classic) and Steely Gray (Sherwin-Williams) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. The 24-point LRV gap — 30 for Steely Gray vs 6 for Black grey — means Steely Gray will open up a space more effectively. A ΔE of 41.5 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black grey vs Steely Gray in Real Spaces
2 real rooms side by side. Seeing Black grey and Steely Gray 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. Steely Gray reflects noticeably more light off the walls, making the space read more open than Black grey.
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. Steely Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

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