Sherwin Williams

Copper Mountain

SW 6356

Copper Mountain (SW, #A6613C) is a medium-dark orange with distinct red-brown undertones, registering an LRV of 17. At this low reflectance, it reads rich and grounded, particularly in rooms with moderate to ample natural light. The hue evokes the quality of weathered copper, carrying enough depth to avoid appearing overly saturated while retaining clear warmth.

It pairs well with Sherwin-Williams Shoji White and Accessible Beige as lighter counterpoints that temper its density. Creamy offers a softer trim option, and cooler complements like Rookwood Sash Green or Jasper introduce contrast through blue-green opposition.
