RAL 720-6 vs L366
RAL 720-6 (RAL Effect) and L366 (Tikkurila) 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 4-point LRV gap — 15 for L366 vs 12 for RAL 720-6 — means L366 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.
