Coastal Plain vs Iron Ore
Both from Sherwin-Williams's palette. Coastal Plain reads as green-grey, while Iron Ore reads as grey — two distinct hue families, not close cousins. Coastal Plain (LRV 37) reflects noticeably more light than Iron Ore (LRV 6), a difference of 31 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 39.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
