Thunder vs Agreeable Gray
Where Thunder belongs to Benjamin Moore's range, Agreeable Gray is a Sherwin-Williams color. These are both greige-greys, so the question isn't which hue to choose — it's where within greige-grey to land. Agreeable Gray (LRV 60) reflects noticeably more light than Thunder (LRV 48), a difference of 13 points that becomes especially apparent in rooms with limited natural light. Thunder runs red while Agreeable Gray is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.0 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Thunder vs Agreeable Gray in Real Spaces
6 real rooms side by side. Thunder 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
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 Thunder would.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Thunder.
Kitchen
In a kitchen, colors are seen under bright task lighting that amplifies undertones — what reads neutral elsewhere can show its hand here. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Thunder.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. Agreeable Gray reflects noticeably more light off the walls, making the space read more open than Thunder.
Mudroom
Mudrooms are seen in passing, often under whatever light comes through the door — a context that favors colors with some depth. Agreeable Gray returns significantly more light to the room — in a smaller or darker space, that difference in perceived brightness is hard to miss.
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 Thunder.

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