Rain Sky vs RAL 180-4
Where Rain Sky belongs to Jotun's range, RAL 180-4 is a RAL Effect color. These are both blues, so the question isn't which hue to choose — it's where within blue to land. They have nearly identical light reflectance values (69 vs 71), so they'll read as similarly Light in most lighting conditions. The ΔE 6.2 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
