Eternity vs Purbeck Stone
Where Eternity belongs to Benjamin Moore's range, Purbeck Stone is a Farrow & Ball color. Eternity reads as grey, while Purbeck Stone reads as greige-grey — two distinct hue families, not close cousins. They have nearly identical light reflectance values (52 vs 52), so they'll read as similarly Medium in most lighting conditions. Eternity runs blue while Purbeck Stone is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 6.6 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 2 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
