Flax vs Black grey
Flax (Benjamin Moore) and Black grey (RAL Classic) come from different manufacturers. Hue-wise, Flax belongs to the beige-pink family and Black grey to the blue-grey family. The 35-point LRV gap — 42 for Flax vs 6 for Black grey — means Flax will open up a space more effectively. A ΔE of 51.8 puts these firmly in different territory — two distinct design choices rather than close alternatives.

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