Ocean Swell vs RAL 820-4
Ocean Swell (Behr) and RAL 820-4 (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. The 4-point LRV gap — 23 for RAL 820-4 vs 19 for Ocean Swell — means RAL 820-4 will open up a space more effectively. ΔE 4.0 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Ocean Swell vs RAL 820-4 in Real Spaces
1 real room side by side. Ocean Swell and RAL 820-4 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. RAL 820-4 reads slightly lighter here — a subtle but real difference in how open the space feels.

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.
