Armadillo vs Sand Dune
Where Armadillo belongs to Behr's range, Sand Dune is a Sherwin-Williams color. Both sit in the beige-greige family, which is useful context if you're narrowing within a single hue direction. Armadillo (LRV 50) reflects noticeably more light than Sand Dune (LRV 46), a difference of 4 points that becomes especially apparent in rooms with limited natural light. Armadillo runs red while Sand Dune is decidedly warm, which means they'll respond very differently to warm vs cool light sources. The ΔE 3.3 gap is real but not dramatic — close enough to use together, distinct enough to matter as a choice.
