RAL 660-M vs Mosaic
RAL 660-M is a RAL Effect color while Mosaic comes from Tikkurila. These are both blues, so the question isn't which hue to choose — it's where within blue to land. At LRV 30 vs 24, Mosaic will read as the brighter of the two — a 6-point gap that matters most in north-facing or low-light rooms. At ΔE 8.9, the difference is perceptible but not dramatic — the two can work harmoniously in the same space.
