Cosmic Cobalt vs Iron Ore
Cosmic Cobalt is a Behr color while Iron Ore comes from Sherwin-Williams. Cosmic Cobalt reads as blue, while Iron Ore reads as grey — two distinct hue families, not close cousins. At LRV 10 vs 6, Cosmic Cobalt will read as the brighter of the two — a 4-point gap that matters most in north-facing or low-light rooms. The tonal difference — Cosmic Cobalt's blue character against Iron Ore's neutral — becomes most visible against white trim or in morning light. At ΔE 37.7, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Cosmic Cobalt vs Iron Ore in Real Spaces
2 real rooms side by side. Seeing Cosmic Cobalt and Iron Ore in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. The brightness difference is modest but present — Cosmic Cobalt gives the walls a little more lift.
Front Door
Front doors are seen in isolation against the rest of the facade, which makes them a high-stakes surface where even subtle differences matter. Cosmic Cobalt has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Cosmic Cobalt vs Iron Ore Simulated Comparison
5 simulated room previews — drag the slider on each to see Cosmic Cobalt on one side and Iron Ore 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.
