Atmospheric vs Sioux Falls

Atmospheric and Sioux Falls come from the same Benjamin Moore collection. Hue-wise, Atmospheric belongs to the blue-grey family and Sioux Falls to the blue-green family. The 3-point LRV gap — 33 for Atmospheric vs 29 for Sioux Falls — means Atmospheric will open up a space more effectively. Where Atmospheric leans green and blue, Sioux Falls reads green — a distinction that shifts noticeably depending on the light source and surrounding finishes. ΔE 4.0 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.
