Benjamin Moore

Ash Blue

2057-40

Ash Blue is a smoky medium blue from Benjamin Moore with noticeable green undertones and an LRV of 30.24, positioning it as a mid-tone that absorbs more light than it reflects. The green cast prevents it from reading as a pure blue and gives it a slightly muted, grayed-down quality on walls. It tends to shift cooler under fluorescent lighting and warmer in south-facing rooms.

Simply White and Chantilly Lace provide clean contrast on trim, Hale Navy deepens the palette on accent walls, and Wythe Blue offers a lighter tonal step within the same color range.

LRV measures how much light a color reflects, from 0 (black) to 100 (pure white). Below about 50 a color needs good lighting to avoid going flat, 60 and up helps brighten a room, and most whites sit above 80.
