No, they are not identical. Gossamer Blue is a Benjamin Moore color with medium blue-gray undertones and an LRV of 29.44. Limitless is a PPG color with medium blue-gray undertones and an LRV of 30. With a Delta E of 2.1, 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 2.1, 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.
