Sioux Falls vs Underseas
Where Sioux Falls belongs to Benjamin Moore's range, Underseas is a Sherwin-Williams color. Sioux Falls reads as blue-green, while Underseas reads as green-grey — two distinct hue families, not close cousins. Sioux Falls (LRV 29) reflects noticeably more light than Underseas (LRV 25), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Sioux Falls runs green while Underseas is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. At ΔE 2.8, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
