Urban Walk vs RAL 770-4

The 5-point LRV gap — 25 for Urban Walk vs 20 for RAL 770-4 — means Urban Walk will open up a space more effectively. ΔE 5.5 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Urban Walk vs RAL 770-4 in Real Spaces
1 real room side by side. Urban Walk and RAL 770-4 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.
