Calm Sea vs RAL 180-2
Calm Sea (PPG) and RAL 180-2 (RAL Effect) come from different manufacturers. These are both blues, so the question isn't which hue to choose — it's where within blue to land. The 6-point LRV gap — 64 for Calm Sea vs 58 for RAL 180-2 — means Calm Sea will open up a space more effectively. ΔE 4.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.
