Starry Night vs RAL 640-4
Starry Night is a PPG color while RAL 640-4 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 13 vs 7, Starry Night will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. At ΔE 4.3, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
