Mountain Stream vs Peacock Plume

Mountain Stream and Peacock Plume come from the same Sherwin-Williams collection. Mountain Stream reads as blue, while Peacock Plume reads as blue-grey — two distinct hue families, not close cousins. Their light reflectance values are nearly the same — 25 vs 28 — 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. ΔE 6.3 means they're clearly different, but not dramatically so — they'd pair well in the same room.
