Big Sky vs Open Air
Where Big Sky belongs to PPG's range, Open Air is a Sherwin-Williams color. Both sit in the blue family, which is useful context if you're narrowing within a single hue direction. Big Sky (LRV 73) reflects noticeably more light than Open Air (LRV 70), a difference of 3 points that becomes especially apparent in rooms with limited natural light. At ΔE 3.0, these are close — the kind of difference that matters when choosing between them, but doesn't read strongly in a finished room.
