Senora Gray vs Thunder
Both from Benjamin Moore's palette. Hue-wise, Senora Gray belongs to the beige-greige family and Thunder to the greige-grey family. They have nearly identical light reflectance values (48 vs 48), so they'll read as similarly Medium in most lighting conditions. Senora Gray runs yellow while Thunder is decidedly red, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
Senora Gray vs Thunder in Real Spaces
1 real room side by side. Senora Gray and Thunder 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. Side by side like this, the difference is easy to read — which is exactly why seeing them in a real space is more useful than comparing chips.

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.
