Impromptu vs Stratford Blue

Impromptu and Stratford Blue come from the same Sherwin-Williams collection. These are both blues, so the question isn't which hue to choose — it's where within blue to land. Their light reflectance values are nearly the same — 23 vs 22 — so neither will read significantly brighter or darker than the other. Both share a cool character, which means they'll respond to light and surrounding materials in similar ways. A ΔE of 15.5 puts these firmly in different territory — two distinct design choices rather than close alternatives.
