The color of the ocean on an overcast day. Calm and confident. To find a good PPG match, we need a color that captures not just the right depth (LRV 28) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Compass Blue 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 good news: there is a strong PPG match for Compass Blue. Limitless (PPG1091-4) comes in with a Delta E of 2.3, which puts it in the "excellent match" range. Limitless is the closest PPG option. Very close match.

Frequently Asked Questions
The closest PPG match for Compass Blue (PPU13-08) is Limitless (PPG1091-4) with a Delta E of 2.3, which rates as a "excellent match" match. Limitless is the closest PPG 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. Compass Blue is a Behr color with medium blue-gray undertones and an LRV of 28. Limitless is a PPG color with medium blue-gray undertones and an LRV of 30. With a Delta E of 2.3, 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 2.3, 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 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.
