RAL 740-5 vs M371
RAL 740-5 is a RAL Effect color while M371 comes from Tikkurila. These are both blues, so the question isn't which hue to choose — it's where within blue to land. With LRVs of 7 and 6, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 6.7, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Before committing to either color, test physical samples in your own space under the light you actually live with.
