Iron Mountain vs Mizzle
Where Iron Mountain belongs to Benjamin Moore's range, Mizzle is a Farrow & Ball color. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Mizzle (LRV 52) reflects noticeably more light than Iron Mountain (LRV 11), a difference of 41 points that becomes especially apparent in rooms with limited natural light. Iron Mountain runs red while Mizzle is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 42.2, 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.
