Marine Blue vs Iron Ore
Marine Blue (Benjamin Moore) and Iron Ore (Sherwin-Williams) come from different manufacturers. Marine Blue reads as blue, while Iron Ore reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 6 vs 6 — so neither will read significantly brighter or darker than the other. Where Marine Blue leans blue, Iron Ore reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 21.3 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.

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