Charcoal Slate vs Cannon Ball
Charcoal Slate (Benjamin Moore) and Cannon Ball (Dulux) come from different manufacturers. These are both greys, so the question isn't which hue to choose — it's where within grey to land. The 4-point LRV gap — 15 for Charcoal Slate vs 11 for Cannon Ball — means Charcoal Slate will open up a space more effectively. Where Charcoal Slate leans blue, Cannon Ball reads neutral — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 8.4 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 6 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
Charcoal Slate vs Cannon Ball in Real Spaces
6 real rooms side by side. Charcoal Slate and Cannon Ball 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
A living room wall sees more varied light than almost any other surface in the house, which makes the choice between these two more nuanced than a chip suggests. Charcoal Slate reads slightly lighter here — a subtle but real difference in how open the space feels.
Bedroom
Bedrooms are typically lit with warmer, lower light than the rest of the house — a condition that flatters warm tones and deepens cool ones. Charcoal Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen
Kitchens often have the harshest, most revealing light in the house — under-cabinet LEDs and overhead fixtures that strip away subtlety. Charcoal Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Bathroom
Small bathrooms intensify color. A shade that seems quiet in a larger room can feel immersive when you're surrounded by it on four walls. Charcoal Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Home Office
Home office walls matter more than most — you're looking at them all day, and a color that reads fine at first can become tiring over time. Charcoal Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.
Kitchen Cabinets
Cabinet color is always seen in context — against countertops, backsplash, and hardware — which amplifies undertone differences that might disappear on a plain wall. Charcoal Slate has the edge in reflectance, which shows as a quiet sense of added space rather than an obvious contrast.

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