Finding a Behr Equivalent for Copley Gray

If you love Benjamin Moore Copley Gray 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.

Copley Gray (HC-104) is a medium-dark green with muted olive-gray undertones. A complex olive-gray from the Historical Collection. More olive than Sandy Hook Gray, more gray than a true green. One of BM's most sophisticated exterior colors, it reads as earthy and historic. To find a good Behr match, we need a color that captures not just the right depth (LRV 30.85) but also that specific undertone character. That is where Delta E color science comes in.

We calculated the perceptual color distance between Copley Gray 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 Sage Green (PPU11-07) with a Delta E of 4.8, which is a "good match" level match. Sage Green is brighter. Copley Gray is more muted and olive-toned. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.
