Signal black vs Black grey
Both from RAL Classic's palette. They have nearly identical light reflectance values (6 vs 6), so they'll read as similarly dark in most lighting conditions. The ΔE 3.4 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
Signal black vs Black grey Color Comparison
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.

Signal black vs Black grey in Real Spaces
Signal black and Black grey are close enough that the difference can be hard to judge from a chip alone. These real-room photos show how each reads at scale, across different spaces and lighting conditions. Showing 3 room types where both colors have photos.
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.

House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. The distinction reads clearly at room scale, making the choice between them concrete.

Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. The distinction reads clearly at room scale, making the choice between them concrete.
