RAL 580-M vs Plummy
RAL 580-M (RAL Effect) and Plummy (Sherwin-Williams) come from different manufacturers. RAL 580-M reads as blue, while Plummy reads as grey — two distinct hue families, not close cousins. The 4-point LRV gap — 15 for RAL 580-M vs 11 for Plummy — means RAL 580-M will open up a space more effectively. A ΔE of 10.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate.

Before committing to either color, test physical samples in your own space under the light you actually live with.
