Mountain Air vs Sky High

Both from Sherwin-Williams's palette. Mountain Air reads as blue-grey, while Sky High reads as blue — two distinct hue families, not close cousins. Sky High (LRV 78) reflects noticeably more light than Mountain Air (LRV 73), a difference of 5 points that becomes especially apparent in rooms with limited natural light. Both lean cool, so they'll behave similarly in mixed or changing light conditions. At ΔE 2.7, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
