What color is Sherwin Williams Slate Violet?
Sherwin Williams Slate Violet SW 9155 is a muted midtone gray with a faint dusty violet and rosy cast. Its low-saturation character keeps the color restrained, so it can read almost like a softened warm gray in some settings. Warm bulbs tend to pull forward its subtle blush notes, while cooler daylight makes the gray-violet side more noticeable. It suits bedrooms, living rooms, and home offices where a neutral wall color needs a little more personality than standard gray. Pair Slate Violet with soft white trim, charcoal accents, pale oak, brushed nickel, or linen upholstery for a quietly layered look.

What are Sherwin Williams Slate Violet undertones?

LRV of Slate Violet
Slate Violet has an LRV of 29.08% and refers to Medium colors that reflect a lot of 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 29.08%, 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.
