Flashy Sapphire vs RAL 640-5
Flashy Sapphire is a Behr color while RAL 640-5 comes from RAL Effect. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 8 and 6, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 5.5, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
