Auger Shell vs Mount Etna
Auger Shell and Mount Etna come from the same Sherwin-Williams collection. Auger Shell reads as grey, while Mount Etna reads as blue-grey — two distinct hue families, not close cousins. The 24-point LRV gap — 30 for Auger Shell vs 6 for Mount Etna — means Auger Shell will open up a space more effectively. Where Auger Shell leans neutral, Mount Etna reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 33.4 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Auger Shell vs Mount Etna in Real Spaces
3 real rooms side by side. Seeing Auger Shell 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
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. Auger Shell reflects noticeably more light off the walls, making the space read more open than Mount Etna.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Auger Shell will make the room feel meaningfully brighter than Mount Etna would.
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. Auger Shell returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

5 simulated room previews — drag the slider on each to see Auger Shell on one side and Mount Etna 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.
