Plummy vs Seawashed Glass
Both from Sherwin-Williams's palette. Plummy reads as grey, while Seawashed Glass reads as green — two distinct hue families, not close cousins. Seawashed Glass (LRV 48) reflects noticeably more light than Plummy (LRV 11), a difference of 37 points that becomes especially apparent in rooms with limited natural light. Plummy runs cool while Seawashed Glass is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 54.4, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
