RAL 840-1 vs Mortar
RAL 840-1 (RAL Effect) and Mortar (Sherwin-Williams) come from different manufacturers. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. The 3-point LRV gap — 77 for RAL 840-1 vs 74 for Mortar — means RAL 840-1 will open up a space more effectively. A ΔE of 1.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
