Solitude vs RAL 820-2
Solitude (Benjamin Moore) and RAL 820-2 (RAL Effect) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 42 vs 42 — so neither will read significantly brighter or darker than the other. A ΔE of 2.4 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.
Solitude vs RAL 820-2 in Real Spaces
1 real room side by side. Solitude and RAL 820-2 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.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. In photos like these you're seeing the difference at its most direct. In a finished room, the distinction is there but not dramatic.

Solitude vs RAL 820-2 Simulated Comparison
5 simulated room previews — drag the slider on each to see Solitude on one side and RAL 820-2 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.
