What color is Sherwin Williams Green Onyx?
Sherwin Williams Green Onyx SW 9128 is a muted, medium-light green with a noticeable gray cast and soft olive undertones. Its low saturation keeps it from reading bright, giving walls a grounded, gently weathered look. In warm daylight or incandescent lighting, the yellow-green side becomes more apparent, while cooler light can make this shade appear quieter and grayer. Green Onyx suits living rooms, bedrooms, mudrooms, or kitchen cabinetry where a restrained natural color is wanted. Pair it with warm white trim, pale oak, brushed brass, charcoal accents, or clay-toned textiles to reinforce its earthy character.

What are Sherwin Williams Green Onyx undertones?
Green Onyx reads as a muted, midtone yellow-green with low saturation, giving it a softened olive character rather than a bright green. Within its green family, the visible bias leans yellow, which can make it appear warmer and earthier than a blue-leaning green; Sherwin-Williams identifies it simply as a green and does not state an undertone on the provided page. Warm artificial light may bring out more of its yellow cast, while cool daylight may make its green side more noticeable, though surrounding colors and finish can affect the result.

LRV of Green Onyx
Green Onyx has an LRV of 31.41% 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 31.41%, 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.
