Finding a Behr Equivalent for Nantucket Fog
If you love Benjamin Moore Nantucket Fog but need a Behr 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 Behr, your local store does not carry Benjamin Moore, or you simply want to compare prices across brands before committing.
Nantucket Fog (AC-22) is a medium gray with cool neutral undertones. A light-medium cool gray with almost no undertone. One of the most truly neutral grays in the BM lineup. To find a good Behr match, we need a color that captures not just the right depth (LRV 52.37) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Nantucket Fog and every Behr 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 Behr option is Dolphin Fin (PPU26-06) with a Delta E of 4.3, which is a "good match" level match. Dolphin Fin is warmer. Nantucket Fog is more neutral. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.

Dolphin Fin has warm greige undertones. A warm medium gray with subtle beige undertones. Behr's answer to the greige trend. Balanced and versatile.
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. Nantucket Fog's cool neutral quality may read differently than Dolphin Fin's warm greige 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.

With a Delta E of 4.3, the difference is enough that they should not be used on adjacent walls in the same room. You can use them in separate rooms of the same house, but be aware that walking from one room to the other may reveal the difference, especially if the rooms have similar lighting.

Availability matters if your nearest paint store or home center specializes in Behr. Some painters have strong preferences for one brand's formula based on coverage, dry time, or workability.
