Armory vs Mount Etna
Both from Sherwin-Williams's palette. Hue-wise, Armory belongs to the grey family and Mount Etna to the blue-grey family. They have nearly identical light reflectance values (5 vs 6), so they'll read as similarly Dark in most lighting conditions. Armory runs neutral while Mount Etna is decidedly cool, which means they'll respond very differently to warm vs cool light sources. The ΔE 8.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Armory vs Mount Etna in Real Spaces
3 real rooms side by side. Armory and Mount Etna 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The temperature contrast between Mount Etna and Armory is what sets these apart most in this context.
Dining Room
A dining room lit by a dimmed pendant or candles is one of the most forgiving environments for paint — warm light softens almost everything. Armory reads more restrained here, while Mount Etna adds a sense of enclosure and warmth.
Home Office
The test for a home office color isn't how it looks in a quick glance — it's whether it still feels right after a full day of work. Mount Etna brings more warmth to the space, while Armory keeps things cooler and crisper.

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.
