Porringer Gray vs RAL 820-1
Porringer Gray (Benjamin Moore) and RAL 820-1 (RAL Effect) come from different manufacturers. Both sit in the blue-grey family, which is useful context if you're narrowing within a single hue direction. Their light reflectance values are nearly the same — 57 vs 57 — so neither will read significantly brighter or darker than the other. A ΔE of 0.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Porringer Gray vs RAL 820-1 in Real Spaces
2 real rooms side by side. Porringer Gray and RAL 820-1 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.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Porringer Gray vs RAL 820-1 Simulated Comparison
5 simulated room previews — drag the slider on each to see Porringer Gray on one side and RAL 820-1 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.
