Sherwin Williams

Slate Violet

SW 9155

Slate Violet is a medium-depth gray from Sherwin-Williams with a distinct purple undertone that separates it from standard warm or cool grays. Its Light Reflectance Value of 29 means it sits in the lower-medium range, absorbing more light than it reflects and reading as a substantive mid-tone on walls. The violet shift is subtle enough to register as a tinted neutral rather than a true purple.

This color is often used in bedrooms, dining rooms, and accent applications where a deeper wall tone is desired. It coordinates with Sherwin-Williams Passive, Agreeable Gray, Iron Ore, Repose Gray, and Opalescent Pearl.
