Black Iron vs Lamp Black

Black IronBenjamin MoorevsLamp BlackLittle GreeneΔE 6.8Noticeable difference

Black Iron (Benjamin Moore) and Lamp Black (Little Greene) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 3-point LRV gap — 6 for Black Iron vs 3 for Lamp Black — means Black Iron will open up a space more effectively. Where Black Iron leans blue, Lamp Black reads purple — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 6.8 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.

Black Iron vs Lamp Black in Real Spaces

2 real rooms side by side. Black Iron and Lamp Black are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.

Bedroom

Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Black Iron has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
