Mountain Air vs Waterloo
Both from Sherwin-Williams's palette. Hue-wise, Mountain Air belongs to the blue-grey family and Waterloo to the blue family. Mountain Air (LRV 73) reflects noticeably more light than Waterloo (LRV 13), a difference of 60 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. With a ΔE of 46.6, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question.

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.
