Magnetic Gray (SW 7058) is a medium gray with cool neutral gray undertones. A clean, cool mid-tone gray. One of SW's most neutral grays with minimal undertone pull. To find a good Behr match, we need a color that captures not just the right depth (LRV 42) but also that specific undertone character. That is where Delta E color science comes in.
We calculated the perceptual color distance between Magnetic Gray 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.
The results are decent but not perfect. The closest Behr option is Pewter Mug (PPU18-16) with a Delta E of 4.4, which is a "good match" level match. Pewter Mug is warmer. Magnetic Gray is cooler and more neutral. You will want to test a sample before committing, as the difference may be noticeable in certain lighting.
