Fahm vs Black grey
Fahm (Jotun) and Black grey (RAL Classic) come from different manufacturers. Fahm reads as grey, while Black grey reads as blue-grey — two distinct hue families, not close cousins. The 8-point LRV gap — 14 for Fahm vs 6 for Black grey — means Fahm will open up a space more effectively. A ΔE of 24.0 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Fahm vs Black grey in Real Spaces
2 real rooms side by side. Seeing Fahm 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. Fahm 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. Fahm has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Fahm vs Black grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Fahm 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.
