Sherwin Williams

Acier

SW 9170

Acier (hex #9E9991) is a medium-depth neutral with a cool, stone-like undertone balanced by a slight warm cast. At an LRV of 32, it falls in the low-mid brightness range, reading as a taupe-gray blend with low chroma and an earthy base. It avoids feeling sterile due to its balanced warm-cool composition.

Sherwin-Williams Mindful Gray or Repose Gray work well for a layered, tonal interior alongside Acier, while darker anchors like Iron Ore or Greenblack provide clear contrast. Crisp whites such as Pure White or Snowbound highlight its softness without overpowering the wall color.
