Black grey vs Granite grey
Both from RAL Classic's palette. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (6 vs 8), so they'll read as similarly Dark in most lighting conditions. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Black grey vs Granite grey in Real Spaces
2 real rooms side by side. Black grey and Granite 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.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. 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.

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