Highland Mist vs Coastal Plain
Highland Mist (Dulux) and Coastal Plain (Sherwin-Williams) come from different manufacturers. These are both green-greys, so the question isn't which hue to choose — it's where within green-grey to land. Their light reflectance values are nearly the same — 38 vs 37 — so neither will read significantly brighter or darker than the other. Both share a neutral character, which means they'll respond to light and surrounding materials in similar ways. ΔE 4.6 means they're clearly different, but not dramatically so — they'd pair well in the same room. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.
