Iron Gate vs Mineral Alloy
Both from Benjamin Moore's palette. Hue-wise, Iron Gate belongs to the greige-grey family and Mineral Alloy to the blue-grey family. Mineral Alloy (LRV 28) reflects noticeably more light than Iron Gate (LRV 23), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Iron Gate runs red while Mineral Alloy is decidedly blue, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 17.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
