Sioux Falls vs Iron Ore
Where Sioux Falls belongs to Benjamin Moore's range, Iron Ore is a Sherwin-Williams color. Sioux Falls reads as blue-green, while Iron Ore reads as grey — two distinct hue families, not close cousins. Sioux Falls (LRV 29) reflects noticeably more light than Iron Ore (LRV 6), a difference of 24 points that becomes especially apparent in rooms with limited natural light. Sioux Falls runs green while Iron Ore is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 32.7, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
