Tundra vs Iron Ore
Where Tundra belongs to Benjamin Moore's range, Iron Ore is a Sherwin-Williams color. Tundra reads as white, while Iron Ore reads as grey — two distinct hue families, not close cousins. Tundra (LRV 77) reflects noticeably more light than Iron Ore (LRV 6), a difference of 72 points that becomes especially apparent in rooms with limited natural light. Tundra runs green while Iron Ore is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 62.1, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
