Lamp Black vs Mortar
Lamp Black (Little Greene) and Mortar (Sherwin-Williams) come from different manufacturers. Lamp Black reads as grey, while Mortar reads as beige-greige — two distinct hue families, not close cousins. The 71-point LRV gap — 74 for Mortar vs 3 for Lamp Black — means Mortar will open up a space more effectively. Where Lamp Black leans purple, Mortar reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 70.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.
