Etched Glass vs Mountain Air
Etched Glass (Behr) and Mountain Air (Sherwin-Williams) come from different manufacturers. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 75 vs 73 — so neither will read significantly brighter or darker than the other. Where Etched Glass leans blue, Mountain Air reads cool — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 1.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Etched Glass vs Mountain Air in Real Spaces
1 real room side by side. Etched Glass and Mountain Air 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.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

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.
