Acorn vs Iron Ore
Acorn (Benjamin Moore) and Iron Ore (Sherwin-Williams) come from different manufacturers. Acorn reads as beige-greige, while Iron Ore reads as grey — two distinct hue families, not close cousins. The 15-point LRV gap — 21 for Acorn vs 6 for Iron Ore — means Acorn will open up a space more effectively. Where Acorn leans red, Iron Ore reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 33.2 puts these firmly in different territory — two distinct design choices rather than close alternatives.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
