The 4-point LRV gap — 24 for Blue Dusk vs 20 for RAL 620-3 — means Blue Dusk will open up a space more effectively. ΔE 3.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Blue Dusk vs RAL 620-3 in Real Spaces
1 real room side by side. Blue Dusk and RAL 620-3 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. Blue Dusk has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Blue Dusk vs RAL 620-3 Simulated Comparison
5 simulated room previews — drag the slider on each to see Blue Dusk on one side and RAL 620-3 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.
