Mountain Air vs Topsail
Mountain Air and Topsail come from the same Sherwin-Williams collection. Hue-wise, Mountain Air belongs to the blue-grey family and Topsail to the blue-green family. Their light reflectance values are nearly the same — 73 vs 75 — 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. A ΔE of 0.9 puts them in subtle territory — distinguishable in direct comparison, less so from across a 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.
