What color is Sherwin Williams Portsmouth?
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.

LRV of Portsmouth
Portsmouth has an LRV of 21.94% and refers to Medium colors that reflect a lot of light. Why LRV is important?
Light Reflectance Value measures the amount of visible and usable light that reflects from a painted surface.
Simply put, the higher the LRV of a paint color, the brighter the room you will get.
The scale goes from 0% (absolute black, absorbing all light) to 100% (pure white, reflecting all light).
Act like a pro: When choosing paint with an LRV of 21.94%, pay attention to your bulbs' brightness. Light brightness is measured in lumens. The lower the paint's LRV, the higher lumen level you need. Every square foot of room needs at least 40 lumens. That means for a 200 ft2 living room you'll need about 8000 lumens of light – e.g., eight 1000 lm bulbs.
