Charcoal Blue vs Iron Ore
Charcoal Blue and Iron Ore come from the same Sherwin-Williams collection. Charcoal Blue reads as blue-grey, while Iron Ore reads as grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 6 vs 6 — so neither will read significantly brighter or darker than the other. Where Charcoal Blue leans cool, Iron Ore reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 9.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Charcoal Blue vs Iron Ore in Real Spaces
8 real rooms side by side. Charcoal Blue and Iron Ore 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.
Living Room
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Iron Ore brings more warmth to the space, while Charcoal Blue keeps things cooler and crisper.
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. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.
Front Door
On a front door, the color is both the first and last thing you see — a context where even a modest tonal difference reads clearly. Iron Ore brings more warmth to the space, while Charcoal Blue keeps things cooler and crisper.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Charcoal Blue reads more restrained here, while Iron Ore adds a sense of enclosure and warmth.

5 simulated room previews — drag the slider on each to see Charcoal Blue 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.
