Finding a Benjamin Moore Equivalent for Smoky Slate

If you love Behr Smoky Slate but need a Benjamin Moore alternative, you are not alone. This is one of the most common cross-brand paint matching searches, whether you are working with a painter who prefers Benjamin Moore, your local store does not carry Behr, or you simply want to compare prices across brands before committing.

Smoky Slate (PPU25-18) is a dark gray with cool dark charcoal undertones. A cool, dark charcoal with minimal undertone. Behr's cleanest dark gray. Serious and commanding without the warmth of Porpoise or the brown of Mineral. To find a good Benjamin Moore match, we need a color that captures not just the right depth (LRV 8) but also that specific undertone character. That is where Delta E color science comes in.

We calculated the perceptual color distance between Smoky Slate and every Benjamin Moore color using the CIE2000 Delta E formula, which measures how different two colors look to the human eye. A Delta E under 2 means most people cannot tell the colors apart. Between 2 and 4, you might notice a difference in certain lighting. Above 5, the difference is clearly visible side by side.

The results are decent but not perfect. The closest Benjamin Moore option is Kendall Charcoal (HC-166) with a Delta E of 4.8, which is a "good match" level match. Kendall Charcoal is greener. Smoky Slate is more neutral. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.

Undertone Comparison

Smoky Slate has cool dark charcoal undertones. A cool, dark charcoal with minimal undertone. Behr's cleanest dark gray. Serious and commanding without the warmth of Porpoise or the brown of Mineral.

Kendall Charcoal has warm green-gray undertones. A deep, warm charcoal with subtle green undertones. Dark enough to make a statement without going full black.

The undertone difference is worth paying attention to. While they are close in overall appearance, the different undertones mean they may diverge in certain lighting. Smoky Slate's cool dark charcoal quality may read differently than Kendall Charcoal's warm green-gray character, especially in rooms with strong directional light or colored accents that could pull out one undertone more than the other. Test a sample in your specific room before committing.
