Rockweed vs Superwhite
Both from Sherwin-Williams's palette. Rockweed reads as grey, while Superwhite reads as grey-white — two distinct hue families, not close cousins. Rockweed (LRV 4) reflects noticeably more light than Superwhite (LRV 0), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Rockweed runs warm while Superwhite is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 68.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
