Benjamin Moore

Slate Blue

1648 / CC-818

Slate Blue is a desaturated, mid-value blue carrying distinct gray undertones that prevent it from reading too vivid on the wall. With an LRV of 43.21, it occupies the middle of the reflectance scale, providing moderate depth without darkening a space significantly. The gray cast shifts slightly cooler under fluorescent light and stays relatively stable under warm incandescent sources.

Balboa Mist and Edgecomb Gray offer warm neutral counterpoints that balance the coolness, while Palladian Blue extends a tonal blue-green range. Kendall Charcoal delivers sharp contrast, and White Dove serves as a reliable trim choice.
