A classic F&B dark neutral. To find a good Behr match, we need a color that captures not just the right depth (LRV 10) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Down Pipe 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 Down Pipe. Underground (PPU18-02) comes in with a Delta E of 2, which puts it in the "excellent match" range. Underground is the closest Behr option. Very close match.

Undertone Comparison
Down Pipe has warm green-gray undertones. A deep, warm dark gray with subtle green undertones. Softer and warmer than Railings, less blue than Off-Black. A classic F&B dark neutral.
Underground has warm dark charcoal undertones. A warm, dark charcoal-brown. Deeper than Off Broadway, lighter than Granite Boulder. The warm brown gives it an earthy, organic quality at a very dark depth.
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. Down Pipe's warm green-gray quality may read differently than Underground's warm dark charcoal 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 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.

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.
