Fountain vs Umber Rust
Both from Sherwin-Williams's palette. Fountain reads as blue, while Umber Rust reads as beige — two distinct hue families, not close cousins. Fountain (LRV 39) reflects noticeably more light than Umber Rust (LRV 10), a difference of 29 points that becomes especially apparent in rooms with limited natural light. Fountain runs cool while Umber Rust is decidedly warm, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 61.2, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.
