Harmonic Tan vs Sea Mariner
Both from Sherwin-Williams's palette. Harmonic Tan reads as beige, while Sea Mariner reads as blue-grey — two distinct hue families, not close cousins. Harmonic Tan (LRV 45) reflects noticeably more light than Sea Mariner (LRV 7), a difference of 38 points that becomes especially apparent in rooms with limited natural light. Harmonic Tan runs warm while Sea Mariner is decidedly cool, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 51.0, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
