Where Ambler Slate leans blue, Iron Ore reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 9.6 means they're clearly different, but not dramatically so — they'd pair well in the same room.

Ambler Slate vs Iron Ore in Real Spaces
2 real rooms side by side. Ambler Slate 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.
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. Ambler Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Ambler Slate reads slightly lighter here — a subtle but real difference in how open the space feels.

5 simulated room previews — drag the slider on each to see Ambler Slate 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.
