Black Iron vs Deep Space

Black IronBenjamin MoorevsDeep SpaceBenjamin MooreΔE 11.2Distinct difference

Black Iron and Deep Space come from the same Benjamin Moore collection. Hue-wise, Black Iron belongs to the grey family and Deep Space to the blue-grey family. The 5-point LRV gap — 11 for Deep Space vs 6 for Black Iron — means Deep Space will open up a space more effectively. Both share a blue character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 11.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

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.
