Rust vs RAL 390-M
Where Rust belongs to Benjamin Moore's range, RAL 390-M is a RAL Effect color. These are both beige-pinks, so the question isn't which hue to choose — it's where within beige-pink to land. They have nearly identical light reflectance values (20 vs 20), so they'll read as similarly Dark in most lighting conditions. The ΔE 5.7 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Rust vs RAL 390-M in Real Spaces
1 real room side by side. Rust and RAL 390-M 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.

Rust vs RAL 390-M Simulated Comparison
5 simulated room previews — drag the slider on each to see Rust on one side and RAL 390-M 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.
