Finding a PPG Equivalent for Dark Night
If you love Sherwin Williams Dark Night but need a PPG 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 PPG, your local store does not carry Sherwin Williams, or you simply want to compare prices across brands before committing.
Dark Night (SW 6237) is a dark navy with deep navy undertones. A deep, inky navy-black. Darker than Naval, with less blue saturation. Approaches black but retains enough blue to read as the darkest possible navy rather than a true black. To find a good PPG match, we need a color that captures not just the right depth (LRV 3) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Dark Night 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.
Honestly, PPG does not have a perfect equivalent for Dark Night. The closest option is Limitless (PPG1091-4) with a Delta E of 7.6, but at that distance the difference will be visible. Limitless is the closest PPG option at LRV 30. In the same family but noticeably different. Test a sample before committing. If getting this exact color is critical, you may want to explore custom color matching at a PPG store.

Frequently Asked Questions

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. Dark Night is a Sherwin Williams color with deep navy undertones and an LRV of 3. Limitless is a PPG color with medium blue-gray undertones and an LRV of 30. With a Delta E of 7.6, 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 7.6, 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 PPG equivalent. Price differences between brands can be significant on large projects. Availability matters if your nearest paint store or home center specializes in PPG. Some painters have strong preferences for one brand's formula based on coverage, dry time, or workability. And if you are touching up existing PPG work, matching within the same brand gives you the best consistency for seamless results.
