Natural Slate vs Iron Ore
Natural Slate (Dulux) and Iron Ore (Sherwin-Williams) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 25-point LRV gap — 31 for Natural Slate vs 6 for Iron Ore — means Natural Slate 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 32.6 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.
