Mortar vs Starry Night

MortarSherwin-WilliamsvsStarry NightSherwin-WilliamsΔE 8.5 — Noticeable difference

Both are Sherwin-Williams colors. Mortar reads as beige-greige, while Starry Night reads as blue-grey — two distinct hue families, not close cousins. At LRV 74 vs 69, Mortar will read as the brighter of the two — a 5-point gap that matters most in north-facing or low-light rooms. The tonal difference — Mortar's warm character against Starry Night's cool — becomes most visible against white trim or in morning light. At ΔE 8.5, the difference is perceptible but not dramatic — the two can work harmoniously in the same space. 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.
