Frosted Steel reads as blue-grey, while Ammonite reads as beige-greige — two distinct hue families, not close cousins. The 3-point LRV gap — 72 for Frosted Steel vs 69 for Ammonite — means Frosted Steel will open up a space more effectively. Where Frosted Steel leans cool, Ammonite reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 7.9 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Frosted Steel vs Ammonite in Real Spaces
3 real rooms side by side. Frosted Steel and Ammonite 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. Frosted Steel reads slightly lighter here — a subtle but real difference in how open the space feels.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Frosted Steel has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
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. Frosted Steel has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

Frosted Steel vs Ammonite Simulated Comparison
5 simulated room previews — drag the slider on each to see Frosted Steel on one side and Ammonite 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.
