Benjamin Moore

Plum Martini

CSP-540

Plum Martini from Benjamin Moore is a deep, muted purple-gray with restrained plum undertones that read as dark and closely saturated under most lighting conditions. Its LRV of 6.86 means it absorbs the vast majority of ambient light, making it appropriate for creating enclosed, low-light atmospheres in libraries, dining rooms, or bedrooms. Hale Navy and Black Beauty pair well for a tonal dark scheme, while Sea Pearl or Classic Gray lighten the surrounding palette and reduce visual heaviness.

Raspberry Blush and Summer Plum offer analogous color extensions that maintain the purple family without sharp contrast.
