RAL 180-1 vs Blue Grotto
RAL 180-1 (RAL Effect) and Blue Grotto (Sherwin-Williams) come from different manufacturers. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. The NaN-point LRV gap — NaN for Blue Grotto vs 49 for RAL 180-1 — means Blue Grotto will open up a space more effectively. A ΔE of NaN puts these firmly in different territory — two distinct design choices rather than close alternatives.
