Astronomical vs Evergreen Fog
Astronomical (Behr) and Evergreen Fog (Sherwin-Williams) come from different manufacturers. Hue-wise, Astronomical belongs to the grey family and Evergreen Fog to the green-grey family. The 23-point LRV gap — 30 for Evergreen Fog vs 7 for Astronomical — means Evergreen Fog will open up a space more effectively. Where Astronomical leans green, Evergreen Fog reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 31.2 puts these firmly in different territory — two distinct design choices rather than close alternatives. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Astronomical vs Evergreen Fog in Real Spaces
2 real rooms side by side. Seeing Astronomical and Evergreen Fog in actual rooms makes the difference concrete; browse the spaces below to get a feel for how each color lives on a wall.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Evergreen Fog returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Evergreen Fog returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Astronomical vs Evergreen Fog Simulated Comparison
5 simulated room previews — drag the slider on each to see Astronomical on one side and Evergreen Fog 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.
