Guilford Green vs Sidewalk Gray
Guilford Green and Sidewalk Gray come from the same Benjamin Moore collection. Guilford Green reads as beige-green, while Sidewalk Gray reads as blue-grey — two distinct hue families, not close cousins. The 4-point LRV gap — 61 for Sidewalk Gray vs 57 for Guilford Green — means Sidewalk Gray will open up a space more effectively. Where Guilford Green leans yellow, Sidewalk Gray reads blue — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 17.4 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.
Guilford Green vs Sidewalk Gray in Real Spaces
3 real rooms side by side. Seeing Guilford Green and Sidewalk Gray 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. Sidewalk Gray reads slightly lighter here — a subtle but real difference in how open the space feels.
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. Sidewalk Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Sidewalk Gray has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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