Black Iron vs Sapphire Splendor
Black Iron (Benjamin Moore) and Sapphire Splendor (Dulux) come from different manufacturers. Black Iron reads as grey, while Sapphire Splendor reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 6 vs 5 — so neither will read significantly brighter or darker than the other. Where Black Iron leans blue, Sapphire Splendor reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 6.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Black Iron vs Sapphire Splendor in Real Spaces
1 real room side by side. Black Iron and Sapphire Splendor 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 reads more restrained here, while Sapphire Splendor adds a sense of enclosure and warmth.

5 simulated room previews — drag the slider on each to see Black Iron on one side and Sapphire Splendor on the other.
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.
