Valspar

Shadow Mountain

8003-48E

Valspar Shadow Mountain is a deep slate violet with a blue-gray base. It feels shadowed and cool. The color suits bedrooms, offices, built-ins, or exterior shutters where navy feels too expected.

Low lighting may push it look like charcoal with a purple edge. Warm white trim, antique brass, or smoky taupe fabrics give it polish. Use good lighting if covering all four walls.
