Black Iron vs Rust
Both from Benjamin Moore's palette. Hue-wise, Black Iron belongs to the grey family and Rust to the beige-pink family. Rust (LRV 20) reflects noticeably more light than Black Iron (LRV 6), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Black Iron runs blue while Rust is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 53.8, 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.
