Horizon Gray vs Agreeable Gray
Horizon Gray (Benjamin Moore) and Agreeable Gray (Sherwin-Williams) come from different manufacturers. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. The 10-point LRV gap — 60 for Agreeable Gray vs 51 for Horizon Gray — means Agreeable Gray will open up a space more effectively. Where Horizon Gray 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.
Horizon Gray vs Agreeable Gray in Real Spaces
4 real rooms side by side. Horizon Gray 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.
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. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
Dining Room
Dining rooms often rely on warm incandescent or candlelight, which flatters warm undertones and mutes cool ones. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than Horizon Gray would.
Mudroom
In a hardworking space like a mudroom, the depth and warmth of a color reads differently than in a quieter room. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than Horizon Gray would.
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 returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.

Horizon Gray vs Agreeable Gray Simulated Comparison
5 simulated room previews — drag the slider on each to see Horizon Gray 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.
