Prelude vs Slumber Sloth

Both from Sherwin-Williams's palette. Prelude reads as grey, while Slumber Sloth reads as beige-greige — two distinct hue families, not close cousins. Slumber Sloth (LRV 56) reflects noticeably more light than Prelude (LRV 9), a difference of 47 points that becomes especially apparent in rooms with limited natural light. Prelude runs neutral while Slumber Sloth is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 43.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
