Armadillo vs Mount Etna
Both from Sherwin-Williams's palette. Hue-wise, Armadillo belongs to the greige-grey family and Mount Etna to the blue-grey family. Armadillo (LRV 29) reflects noticeably more light than Mount Etna (LRV 6), a difference of 23 points that becomes especially apparent in rooms with limited natural light. Armadillo runs warm while Mount Etna is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 33.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Armadillo vs Mount Etna in Real Spaces
3 real rooms side by side. Seeing Armadillo and Mount Etna in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
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 LRV gap is large enough that Armadillo will make the room feel meaningfully brighter than Mount Etna would.
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. Armadillo returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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. Armadillo reflects noticeably more light off the walls, making the space read more open than Mount Etna.

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.
