Black Iron vs RAL 180-1
Black Iron (Benjamin Moore) and RAL 180-1 (RAL Effect) come from different manufacturers. Hue-wise, Black Iron belongs to the grey family and RAL 180-1 to the blue family. The 42-point LRV gap — 49 for RAL 180-1 vs 6 for Black Iron — means RAL 180-1 will open up a space more effectively. A ΔE of 50.6 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 Iron vs RAL 180-1 in Real Spaces
3 real rooms side by side. Seeing Black Iron and RAL 180-1 in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. RAL 180-1 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. RAL 180-1 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. RAL 180-1 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Black Iron vs RAL 180-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Black Iron on one side and RAL 180-1 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.
