Delft vs Mountain Pass
Both are Sherwin-Williams colors. These are both blue-greys, so the question isn't which hue to choose — it's where within blue-grey to land. At LRV 33 vs 14, Delft will read as the brighter of the two — a 19-point gap that matters most in north-facing or low-light rooms. The tonal difference — Delft's cool character against Mountain Pass's neutral — becomes most visible against white trim or in morning light. At ΔE 20.4, these are genuinely distinct colors — a strong contrast if used together, or a meaningful choice between two different directions. Below, 5 simulated room previews show how each color reads at scale — real-room photos will be added as they become available.

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.
