Blue Iris vs Opalescent

Blue Iris and Opalescent come from the same Sherwin-Williams collection. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Their light reflectance values are nearly the same — 73 vs 75 — 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. A ΔE of 1.0 puts them in subtle territory — distinguishable in direct comparison, less so from across a room.
