Sherwin Williams

Cast Iron

SW 6202

Cast Iron by Sherwin-Williams is a cool, muted green-gray (#64645A) with earthy undertones and an LRV of 12, placing it firmly in the medium-dark range. Its subdued tone carries mineral-like complexity that reveals itself in rooms with ample natural light or layered artificial lighting. The green-gray balance makes it a grounded, structural color suited to cabinetry, accent walls, or exterior trim.

It works well against warm whites like Sherwin-Williams Alabaster or Shoji White, and it can be layered with deeper tones such as Pewter Green, Urbane Bronze, or Rookwood Sash Green for tonal continuity.
