Chiswell BlueBenjamin MoorevsMortarBenjamin MooreΔE 22.3 — Distinct difference

Both from Benjamin Moore's palette. Chiswell Blue reads as blue-grey, while Mortar reads as beige-greige — two distinct hue families, not close cousins. Chiswell Blue (LRV 30) reflects noticeably more light than Mortar (LRV 23), a difference of 7 points that becomes especially apparent in rooms with limited natural light. Chiswell Blue runs blue while Mortar is decidedly red, which means they'll respond very differently to warm vs cool light sources. With a ΔE of 22.3, the contrast is hard to miss. These aren't variations on a theme — they're two different answers to the same question. 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.
