What color is Sherwin Williams Charcoal Blue?

Sherwin Williams Charcoal Blue SW 2739 is a deep, muted blue-gray with a distinctly cool cast. Its low-saturation charcoal base keeps the blue restrained, so it reads more like a softened near-black than a bright navy. In strong daylight, the blue-gray character is easier to see, while evening light can make this shade appear darker and more graphite-like. Charcoal Blue is well suited to studies, dining rooms, exterior trim, or cabinetry where a dark finish feels deliberate without looking pitch black. Pair it with warm white walls, pale oak, brushed brass, or natural linen to bring contrast and warmth around its cool depth.

What are Sherwin Williams Charcoal Blue undertones?

Charcoal Blue reads as a deep, very muted blue with a charcoal-gray cast and low saturation. Sherwin-Williams identifies SW 2739 as a blue, which matches its visible blue main family rather than suggesting a separate, strongly defined undertone. Any secondary bias is subtle, so it can appear close to neutral gray-blue in many settings. Warm artificial light may soften and gray the blue further, while cool daylight can make its blue character look clearer.

LRV of Charcoal Blue

Charcoal Blue has an LRV of 5.67% and refers to Dark colors which means that this color almost does not reflect light. Why LRV is important?

Light Reflectance Value scale illustration

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 5.67%, 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.
