Black Locust vs Fahm
Black Locust (Behr) and Fahm (Jotun) come from different manufacturers. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 13 vs 14 — so neither will read significantly brighter or darker than the other. Where Black Locust leans green, Fahm reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 2.1 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Black Locust vs Fahm in Real Spaces
1 real room side by side. Black Locust and Fahm are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
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. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.

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