Mountain Pass vs Night Watch
Both from Sherwin-Williams's palette. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. Mountain Pass (LRV 14) reflects noticeably more light than Night Watch (LRV 4), a difference of 10 points that becomes especially apparent in rooms with limited natural light. Both lean neutral, so they'll behave similarly in mixed or changing light conditions. With a ΔE of 21.8, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. Below you'll find 1 real-room photo comparison where both colors appear side by side, plus 5 simulated room previews.

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.
