Charcoal Slate vs Stormy Sky
Both are Benjamin Moore colors. These are both greys, so the question isn't which hue to choose — it's where within grey to land. With LRVs of 15 and 14, 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 1.0, the difference is subtle — you'd need them side by side to reliably tell them apart. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Charcoal Slate vs Stormy Sky in Real Spaces
2 real rooms side by side. Charcoal Slate and Stormy Sky 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.
Home Office
In a home office, wall color sits in your peripheral vision for hours at a time, so temperature and undertone matter more than you might expect. 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.

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.
