About Benjamin Moore Copper Mine
With an LRV of 11, Copper Mine is a deep, dramatic shade. It soaks up light in north-facing rooms and looks richest where strong daylight hits it. Its red 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.
Copper Mine works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Browns ground a room and pair naturally with leather, wood and warm metals.
