Gladiator Gray vs Mined Coal
Both are Behr colors. Hue-wise, Gladiator Gray belongs to the greige-grey family and Mined Coal to the grey family. With LRVs of 15 and 15, they'll behave almost identically in terms of how much light they reflect back into a room. They share a yellow quality — useful to know if you're layering them in the same space. At ΔE 4.8, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. Below you'll find 3 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Gladiator Gray vs Mined Coal in Real Spaces
3 real rooms side by side. Gladiator Gray and Mined Coal 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
Living rooms test a color across a full range of conditions — morning sun, afternoon shade, and evening lamp light all shift how both of these read. Mined Coal reads more restrained here, while Gladiator Gray adds a sense of enclosure and warmth.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The temperature contrast between Gladiator Gray and Mined Coal is what sets these apart most in this context.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The temperature contrast between Gladiator Gray and Mined Coal is what sets these apart most in this context.

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.
