Finding a PPG Equivalent for Stonington Gray
If you love Benjamin Moore Stonington Gray but need a PPG alternative, you are not alone.

Stonington Gray (HC-170) is a medium gray with cool blue-gray undertones. A true, cool gray with subtle blue undertones. Reads as a clean, modern gray without warmth. One of BM's most popular cool grays. To find a good PPG match, we need a color that captures not just the right depth (LRV 59.43) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Stonington Gray and every PPG 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 PPG option is Silver Screen (PPG0997-3) with a Delta E of 3.4, which is a "good match" level match. Silver Screen is an excellent match.
