Black grey vs RAL 470-6
Black grey (RAL Classic) and RAL 470-6 (RAL Effect) come from different manufacturers. Black grey reads as blue-grey, while RAL 470-6 reads as pink-red — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 6 vs 7 — so neither will read significantly brighter or darker than the other. A ΔE of 55.9 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 RAL 470-6 in Real Spaces
3 real rooms side by side. Seeing Black grey and RAL 470-6 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. The distinction reads clearly at room scale, making the choice between them concrete.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

Black grey vs RAL 470-6 Simulated Comparison
5 simulated room previews — drag the slider on each to see Black grey on one side and RAL 470-6 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.
