Deep Space vs Black grey
Deep Space (Benjamin Moore) and Black grey (RAL Classic) 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 4-point LRV gap — 11 for Deep Space vs 6 for Black grey — means Deep Space will open up a space more effectively. A ΔE of 15.8 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Deep Space vs Black grey in Real Spaces
4 real rooms side by side. Seeing Deep Space and Black grey 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. Deep Space reads slightly lighter here — a subtle but real difference in how open the space feels.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Deep Space has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Deep Space reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Deep Space has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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