Atlantic Shoreline vs RAL 810-3
Atlantic Shoreline (Behr) and RAL 810-3 (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. The 3-point LRV gap — 23 for RAL 810-3 vs 21 for Atlantic Shoreline — means RAL 810-3 will open up a space more effectively. ΔE 3.1 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Atlantic Shoreline vs RAL 810-3 in Real Spaces
1 real room side by side. Atlantic Shoreline and RAL 810-3 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.
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. At this scale, the choice between them becomes clear in a way that a swatch alone can't communicate.

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.
