Proper Gray (SW 6003) is a medium greige with warm greige undertones. A warm, balanced greige at medium depth. As its name suggests, it is thoroughly proper: balanced, refined, and never extreme. The kind of color that makes a room feel grown-up without feeling stuffy. To find a good Valspar match, we need a color that captures not just the right depth (LRV 51) but also that specific undertone character. That is where Delta E color science comes in.

No, they are not identical. Proper Gray is a Sherwin Williams color with warm greige undertones and an LRV of 51. Stone Mason Gray is a Valspar color with warm stone greige undertones and an LRV of 50. With a Delta E of 2.2, the difference is subtle and mainly visible in direct side-by-side comparison.

With a Delta E of 2.2, 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.

There are several practical reasons to look for a Valspar equivalent. Price differences between brands can be significant on large projects. Availability matters if your nearest paint store or home center specializes in Valspar. Some painters have strong preferences for one brand's formula based on coverage, dry time, or workability. And if you are touching up existing Valspar work, matching within the same brand gives you the best consistency for seamless results.
