Misty Blue vs RAL 170-4
Misty Blue is a Benjamin Moore color while RAL 170-4 comes from RAL Effect. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 69 vs 66, RAL 170-4 will read as the brighter of the two — a 3-point gap that matters most in north-facing or low-light rooms. With a ΔE of 2.5, the difference is subtle — you'd need them side by side to reliably tell them apart.
