Iron Ore vs Limestone
Iron Ore and Limestone come from the same Sherwin-Williams collection. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 8-point LRV gap — 13 for Limestone vs 6 for Iron Ore — means Limestone will open up a space more effectively. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 15.3 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

Iron Ore vs Limestone Simulated Comparison
5 simulated room previews — drag the slider on each to see Iron Ore on one side and Limestone on the other.
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.
