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.

Digital color is approximate. These simulations are generated from the manufacturer's hex values and overlaid on grayscale room photos — your screen's calibration, brightness, and viewing angle all affect how they render. Before committing to either color, test physical samples in your own space under the light you actually live with.
