RailingsFarrow & BallvsBlack greyRAL ClassicΔE 9.9Noticeable difference

Where Railings belongs to Farrow & Ball's range, Black grey is a RAL Classic color. Railings reads as grey, while Black grey reads as blue-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (7 vs 6), so they'll read as similarly Dark in most lighting conditions. The ΔE 9.9 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Railings vs Black grey in Real Spaces

4 real rooms side by side. Railings and Black grey 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

In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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.
