Coastal Fog vs Agreeable Gray
Coastal Fog (Benjamin Moore) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. Hue-wise, Coastal Fog belongs to the beige-greige family and Agreeable Gray to the greige-grey family. The 8-point LRV gap — 60 for Agreeable Gray vs 53 for Coastal Fog — means Agreeable Gray will open up a space more effectively. Where Coastal Fog leans yellow, Agreeable Gray reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 6.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Coastal Fog vs Agreeable Gray in Real Spaces
4 real rooms side by side. Coastal Fog and Agreeable Gray 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
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. Agreeable Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
House
A full exterior is the most demanding test for a paint color — scale and outdoor light both amplify differences that seem small on a swatch. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Agreeable Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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