About Sherwin-Williams Limestone
With an LRV of 13, Limestone is a deep, dramatic shade. It soaks up light in north-facing rooms and looks richest where strong daylight hits it. Its orange undertone is the part to watch: it gets picked up by whatever sits next to it, so test it against your trim, floor and the room's main light before committing. Warm artificial light softens it; cool LED can make it look flat, so match your bulbs to the mood you want.
Limestone works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Greige-leaning neutrals like this are the safe whole-home choice when you want warmth without committing to a color.
