What color is Benjamin Moore Plum Martini?
Benjamin Moore Plum Martini CSP-540 is a deep, near-black charcoal with a restrained plum-gray cast. Its low saturation keeps the color from reading overtly purple, though the subtle violet undertone may become more noticeable in bright natural light. In dim rooms, Plum Martini settles into a soft blackened neutral that adds definition without the sharpness of true black. Use it on cabinetry, a library wall, interior doors, or a powder room for a grounded look. Pair it with warm white trim, pale oak, brushed brass, and muted stone finishes to bring out its quiet warmth.

LRV of Plum Martini
Plum Martini has an LRV of 6.86% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 6.86%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
