What color is Sherwin Williams Acier?
Sherwin Williams Acier SW 9170 is a muted mid-tone gray with a noticeable beige cast, giving it a softly warmed, weathered appearance. Its low saturation keeps the color from reading overly brown or starkly cool, making it especially useful where a plain gray would feel severe. In bright natural light, Acier can look like a pale warm stone; in dimmer rooms, its gray side becomes more apparent. It suits living room walls, bedrooms, and hallways, and can also bring a grounded look to painted cabinetry. Pair it with creamy off-whites, charcoal accents, aged brass, oak, linen, and matte black details for a layered, material-focused interior.

What are Sherwin Williams Acier undertones?
Acier is a mid-light, very muted muted beige. The HEX sample has a subtle yellow-orange bias, but its low chroma turns that hue into a neutral-looking color rather than a clear yellow-orange. Warm bulbs can make it look creamier or more golden, while cool daylight may mute that warmth and pull it closer to beige or greige.

LRV of Acier
Acier has an LRV of 31.99% and refers to Medium colors that reflect a lot of light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 31.99%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
