Tawny Owl vs Umber Rust
Tawny Owl (Dulux) and Umber Rust (Sherwin-Williams) come from different manufacturers. Hue-wise, Tawny Owl belongs to the greige-grey family and Umber Rust to the beige family. Their light reflectance values are nearly the same — 10 vs 10 — so neither will read significantly brighter or darker than the other. Both share a warm character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 17.7 puts these firmly in different territory — two distinct design choices rather than close alternatives.
