Finding a Behr Equivalent for Thunderbird
If you love Benjamin Moore Thunderbird 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.
Thunderbird (675) is a dark blue with smoky blue undertones. A medium-dark smoky blue with gray undertones. Rich enough to make a statement, gray enough to feel neutral. To find a good Behr match, we need a color that captures not just the right depth (LRV 14.15) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Thunderbird 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.
Honestly, Behr does not have a perfect equivalent for Thunderbird. The closest option is Midnight Blue (PPU15-18) with a Delta E of 9, but at that distance the difference will be visible. Midnight Blue is much darker. If getting this exact color is critical, you may want to explore custom color matching at a Behr store.

Midnight Blue has blue-purple undertones. A deep, dramatic navy with subtle purple undertones. Rich and bold, with more purple lean than many navies.
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.

Test a sample in your specific room before committing.

No, they are not identical. Thunderbird is a Benjamin Moore color with smoky blue undertones and an LRV of 14.15. Midnight Blue is a Behr color with blue-purple undertones and an LRV of 5. With a Delta E of 9, you will likely notice a difference, especially in bright or direct lighting. 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 9, 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. For the most consistent look, pick one brand for all connected living spaces and reserve the other brand for visually separate rooms like bathrooms or bedrooms behind closed doors.
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.
