Finding a PPG Equivalent for Intellectual Gray

If you love Sherwin Williams Intellectual Gray 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.

Intellectual Gray (SW 7045) is a medium-dark greige with warm greige undertones. A rich medium greige with warm earthy undertones. Grounding and sophisticated. To find a good PPG match, we need a color that captures not just the right depth (LRV 36) but also that specific undertone character. That is where Delta E color science comes in.

We calculated the perceptual color distance between Intellectual Gray 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 Up In Smoke (PPG0997-4) with a Delta E of 3.7, which is a "good match" level match. Up In Smoke is the closest PPG option at LRV 35. 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

Intellectual Gray has warm greige undertones. A rich medium greige with warm earthy undertones. Grounding and sophisticated.

Up In Smoke has cool medium gray undertones. A cool, clean medium gray. Darker than Cool Concrete, with more presence on the wall. PPG's solid workhorse for rooms that need a definitive gray without warmth or obvious undertones.

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. Intellectual Gray's warm greige quality may read differently than Up In Smoke's cool medium gray 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.
