Imperial Gray vs Agate Grey
Imperial Gray (Benjamin Moore) and Agate Grey (RAL Classic) come from different manufacturers. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 47 vs 45 — so neither will read significantly brighter or darker than the other. A ΔE of 2.2 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.
Imperial Gray vs Agate Grey in Real Spaces
1 real room side by side. Imperial Gray and Agate 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.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Imperial Gray vs Agate Grey Simulated Comparison
5 simulated room previews — drag the slider on each to see Imperial Gray on one side and Agate 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.
