Finding a PPG Equivalent for Oyster White
If you love Sherwin Williams Oyster White 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.
Oyster White (SW 7637) is a light white with warm pearl undertones. A warm, pearly off-white with beige-gray depth. More color than most whites. To find a good PPG match, we need a color that captures not just the right depth (LRV 72) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Oyster White 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 results are decent but not perfect. The closest PPG option is Swirl (PPG1022-2) with a Delta E of 3.7, which is a "good match" level match. Swirl is the closest PPG option at LRV 73. Similar character, though some difference is visible in direct comparison. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.

Undertone Comparison
Oyster White has warm pearl undertones. A warm, pearly off-white with beige-gray depth. More color than most whites.
Swirl has warm swirl cream undertones. A warm, swirling off-white with beige undertones. Named for the gentle motion of cream in coffee. Organic and inviting.
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. Oyster White's warm pearl quality may read differently than Swirl's warm swirl cream 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.

Frequently Asked Questions
The closest PPG match for Oyster White (SW 7637) is Swirl (PPG1022-2) with a Delta E of 3.7, which rates as a "good match" match. Swirl is the closest PPG option at LRV 73. Similar character, though some difference is visible in direct comparison. 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. Oyster White is a Sherwin Williams color with warm pearl undertones and an LRV of 72. Swirl is a PPG color with warm swirl cream undertones and an LRV of 73. With a Delta E of 3.7, 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 3.7, 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.
