Coastal Fog vs Guilford Green
Coastal Fog and Guilford Green come from the same Benjamin Moore collection. Coastal Fog reads as beige-greige, while Guilford Green reads as beige-green — two distinct hue families, not close cousins. The 5-point LRV gap — 57 for Guilford Green vs 53 for Coastal Fog — means Guilford Green will open up a space more effectively. Both share a yellow character, which means they'll respond to light and surrounding materials in similar ways. ΔE 6.9 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 Guilford Green in Real Spaces
4 real rooms side by side. Coastal Fog and Guilford Green 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. Guilford Green 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. Guilford Green 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. Guilford Green 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. Guilford Green has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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