September Morning vs Pure White
September Morning (Behr) and Pure White (Sherwin-Williams) come from different manufacturers. These are both beige-greiges, so the question isn't which hue to choose — it's where within beige-greige to land. Their light reflectance values are nearly the same — 83 vs 84 — so neither will read significantly brighter or darker than the other. Where September Morning leans red, Pure White reads warm — a distinction that shifts noticeably depending on the light source and surrounding finishes. A ΔE of 55.0 puts these firmly in different territory — two distinct design choices rather than close alternatives.
