Gypsum vs Purple Passage
Both from Sherwin-Williams's palette. Gypsum reads as white, while Purple Passage reads as blue-grey — two distinct hue families, not close cousins. Gypsum (LRV 82) reflects noticeably more light than Purple Passage (LRV 12), a difference of 70 points that becomes especially apparent in rooms with limited natural light. Gypsum runs neutral while Purple Passage is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 54.5, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
