Hamilton Blue vs Agreeable Gray
Where Hamilton Blue belongs to Benjamin Moore's range, Agreeable Gray is a Sherwin-Williams color. Hamilton Blue reads as blue-grey, while Agreeable Gray reads as greige-grey — two distinct hue families, not close cousins. Agreeable Gray (LRV 60) reflects noticeably more light than Hamilton Blue (LRV 18), a difference of 42 points that becomes especially apparent in rooms with limited natural light. Hamilton Blue runs blue while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 36.9, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 4 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Hamilton Blue vs Agreeable Gray in Real Spaces
4 real rooms side by side. Seeing Hamilton Blue and Agreeable 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
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than Hamilton Blue would.
House
Seen across an entire facade, subtle tonal differences become pronounced. What reads as nearly the same on a chip often reads as clearly different at scale. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Hamilton Blue.
Front Door
A front door is a focal point — small color differences read clearly at this concentrated scale. The LRV gap is large enough that Agreeable Gray will make the room feel meaningfully brighter than Hamilton Blue would.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Hamilton Blue.

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.
