Cotton White vs Opaline
Both from Sherwin-Williams's palette. Cotton White reads as beige-white, while Opaline reads as green-grey — two distinct hue families, not close cousins. Cotton White (LRV 87) reflects noticeably more light than Opaline (LRV 73), a difference of 14 points that becomes especially apparent in rooms with limited natural light. Cotton White runs warm while Opaline is decidedly neutral, which means they'll respond very differently to warm vs cool light sources. The ΔE 7.8 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
