Imperial Gray vs Charcoal Slate
Imperial Gray is a Behr color while Charcoal Slate comes from Benjamin Moore. Both sit in the grey family, which is useful context if you're narrowing within a single hue direction. With LRVs of 14 and 15, they'll behave almost identically in terms of how much light they reflect back into a room. They share a blue quality — useful to know if you're layering them in the same space. With a ΔE of 1.7, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 5 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Imperial Gray vs Charcoal Slate in Real Spaces
5 real rooms side by side. Imperial Gray and Charcoal Slate 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.
Kitchen
Kitchen lighting tends to be bright and directional, which sharpens contrast and makes undertone differences more apparent. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Dining Room
Dining room light is typically the warmest in the house, which shifts both colors toward the red end of the spectrum compared to daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bathroom
Bathrooms amplify color — the enclosed space and reflective surfaces make what reads subtle elsewhere feel more present here. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
House
At full exterior scale, the difference between these two colors becomes much easier to judge than from a small chip. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Kitchen Cabinets
On cabinetry, undertone and temperature become more pronounced against countertops and hardware. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.

Imperial Gray vs Charcoal Slate Simulated Comparison
5 simulated room previews — drag the slider on each to see Imperial Gray on one side and Charcoal Slate 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.
