Finding a Behr Equivalent for Fog
If you love PPG 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 PPG, or you simply want to compare prices across brands before committing.
Fog (PPG0997-2-2) is a medium gray with cool fog gray undertones. A cool, neutral light gray named for morning fog. Clean and modern. PPG's most popular light neutral gray. To find a good Behr match, we need a color that captures not just the right depth (LRV 52) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between 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 good news: there is a strong Behr match for Fog. Classic Silver (PPU18-12) comes in with a Delta E of 2.2, which puts it in the "excellent match" range. Classic Silver is the closest Behr option. Very close match.

Delta E measures perceptual color distance on a scale where under 2 means nearly identical, 2 to 4 means close with subtle differences, and over 5 means clearly noticeable.
No, they are not identical. Fog is a PPG color with cool fog gray undertones and an LRV of 52. Classic Silver is a Behr color with cool silver undertones and an LRV of 51. With a Delta E of 2.2, the difference is subtle and mainly visible in direct side-by-side comparison. Paint formulations differ between brands, so even colors with similar values can look slightly different due to pigment concentration, binders, and finish.
With a Delta E of 2.2, these colors are close enough to use in separate rooms of the same house without a jarring difference. However, avoid painting them on adjacent walls in the same room, as even subtle differences become apparent at a hard edge where two paints meet. For the smoothest result, use one brand consistently within each connected space and reserve the other brand for rooms that are visually separated.
There are several practical reasons to look for a Behr equivalent. Price differences between brands can be significant on large projects. 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. And if you are touching up existing Behr work, matching within the same brand gives you the best consistency for seamless results.
