Black grey vs Olive green
Black grey and Olive green come from the same RAL Classic collection. Black grey reads as blue-grey, while Olive green reads as green-yellow — two distinct hue families, not close cousins. The 4-point LRV gap — 11 for Olive green vs 6 for Black grey — means Olive green will open up a space more effectively. A ΔE of 20.9 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Black grey vs Olive green in Real Spaces
3 real rooms side by side. Seeing Black grey and Olive green in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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. Olive green 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. Olive green 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. Olive green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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