Pompeian Ash vs Pewter Green
Where Pompeian Ash belongs to Little Greene's range, Pewter Green is a Sherwin-Williams color. Both sit in the green-grey family, which is useful context if you're narrowing within a single hue direction. They have nearly identical light reflectance values (11 vs 12), so they'll read as similarly Dark in most lighting conditions. Pompeian Ash runs green while Pewter Green is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 1.6, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.

Pompeian Ash vs Pewter Green in Real Spaces
4 real rooms side by side. Pompeian Ash and Pewter Green are close enough that the difference can be hard to judge from a chip alone — these photos show how each reads at scale, across different spaces and lighting conditions.
Living Room
In a living room, color works across both daylight and evening light — the same wall can read very differently at noon and at 8pm. The two are close enough that the choice comes down to finer qualities — undertone, texture, what the color sits next to.
Bedroom
The context that matters most in a bedroom is how a color reads under a bedside lamp at night, not under noon daylight. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Bathroom
Bathrooms are one of the few spaces where you're genuinely enclosed by the paint color, which makes the choice between these two more consequential. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
Kitchen Cabinets
Kitchen cabinets are constantly compared against adjacent materials, which means subtle differences between these two become much more visible. At this scale the difference is subtle — you'd need them side by side, as shown here, to reliably tell them apart.
