Idyllic Isle vs RAL 670-3
Idyllic Isle (PPG) and RAL 670-3 (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 8-point LRV gap — 55 for Idyllic Isle vs 47 for RAL 670-3 — means Idyllic Isle will open up a space more effectively. ΔE 3.9 means they're clearly different, but not dramatically so — they'd pair well in the same room.
