Sherwin Williams

Green Onyx

SW 9128

Green Onyx is a muted green with cool undertones that keep it from reading overtly earthy or olive. At an LRV of 31, it occupies the lower-mid range and works well on dining room walls, built-in bookshelves, and exterior accents. Silver Strand and Oyster Bay coordinate as lighter green-gray companions in adjoining rooms.

Naval provides a strong contrasting accent, while Urbane Bronze grounds the palette on trim or furniture. Sea Salt extends the green family at a much lighter value for ceilings or hallways.

Green Onyx in Different Light

Light temperature is measured in Kelvin: a warm 2700K bulb pulls colors toward yellow, while 5000K daylight reads cooler and truer. Check the color at the time of day you actually use the room.
