Sherwin Williams Portsmouth SW 9644 is a muted blue-green gray with a medium depth and a softly weathered appearance. Its balance of gray keeps the color grounded, while the green-blue cast becomes more noticeable in clear daylight. In lower or warmer artificial light, Portsmouth can read as a deeper, quieter charcoal-teal rather than a bright coastal shade. It suits bedrooms, offices, powder rooms, or exterior siding where a subdued color with visible character is wanted. Pair it with warm white trim, pale oak, aged brass, charcoal accents, and natural linen for a layered, understated palette.
