Alabaster vs Sea Serpent
Both from Sherwin-Williams's palette. Alabaster reads as beige-greige, while Sea Serpent reads as blue — two distinct hue families, not close cousins. Alabaster (LRV 82) reflects noticeably more light than Sea Serpent (LRV 7), a difference of 76 points that becomes especially apparent in rooms with limited natural light. Alabaster runs warm while Sea Serpent is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 62.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 8 real-room photo comparisons where both colors appear side by side, plus 5 simulated room previews.
