About Sherwin-Williams Portsmouth
With an LRV of 22, Portsmouth is a deep, dramatic shade. It soaks up light in north-facing rooms and looks richest where strong daylight hits it. Because it carries almost no measurable hue, it stays a true neutral and pairs cleanly with nearly any trim or floor. Warm artificial light softens it; cool LED can make it look flat, so match your bulbs to the mood you want.
Portsmouth works best as a feature — a single wall, built-ins, a study or dining room — rather than wrapping a whole bright space. Teals add character without shouting — good for a vanity, an island or a feature wall.
