Black grey vs Moody Blue
Black grey (RAL Classic) and Moody Blue (Sherwin-Williams) 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 20-point LRV gap — 26 for Moody Blue vs 6 for Black grey — means Moody Blue will open up a space more effectively. A ΔE of 38.6 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.
Black grey vs Moody Blue in Real Spaces
3 real rooms side by side. Seeing Black grey and Moody Blue 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. Moody Blue reflects noticeably more light off the walls, making the space read more open than Black grey.
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. Moody Blue returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Moody Blue 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 Moody Blue Simulated Comparison
5 simulated room previews — drag the slider on each to see Black grey on one side and Moody Blue 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.
