RAL 690-2 vs L366
RAL 690-2 is a RAL Effect color while L366 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 17 and 15, they'll behave almost identically in terms of how much light they reflect back into a room. At ΔE 10.5, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions.
