Iron Mountain vs Welded Iron

Iron Mountain and Welded Iron come from the same Behr collection. These are both greys, so the question isn't which hue to choose — it's where within grey to land. Their light reflectance values are nearly the same — 18 vs 16 — so neither will read significantly brighter or darker than the other. Both share a yellow character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 2.5 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
