Great Green
What Great Green Actually Looks Like
Great Green SW 6430 is a muted, medium-depth green with a distinctly earthy personality. Think dried herbs or a mossy field in late summer. It reads greener than many sage tones but never veers into jewel territory. The color sits at an LRV of 42.9, which places it right in the middle of the lightness scale, meaning it has enough depth to anchor a room without making it feel dark. In strong natural light it can lift toward a soft, almost celery tone. Under warm incandescent bulbs, the olive side comes forward and the color feels warmer and more golden. In north-facing rooms or on overcast days, it leans cooler and more distinctly green.
Great Green Undertones
The primary undertone is green, which probably does not surprise you. But the secondary olive undertone is what gives Great Green its grounded, natural quality. Some designers read a subtle yellow warmth running through it, while others see it as a cooler, more purely botanical green. The truth depends heavily on your lighting and what you pair it with. Next to a warm cream, the olive shows up. Next to a cool gray, it reads greener and fresher. This chameleon quality is part of what makes it interesting, but it also means you should always test a large swatch in your actual room before committing.
Where Great Green Works Best
Great Green works well on walls in living rooms and bedrooms where you want a nature-inspired backdrop that feels calm but not boring. It is strong enough for an accent wall in a space that is otherwise neutral, and it pairs beautifully with natural wood tones, woven textures, and linen. In bathrooms, it gives a spa-like quality without resorting to the usual cool blues and grays. It is an interior-only color in the Sherwin-Williams line. You can use it on all four walls of a smaller room if the light is good, or limit it to a feature wall in a dimmer space to keep things from feeling heavy.
Where to put Great Green
Great Green is a strong bedroom pick because its earthy tone promotes relaxation without the coldness of a blue or gray. Use it on all walls with white bedding and warm wood furniture. The LRV of 42.9 means it will feel cozy in evening lamplight but not cave-like in the morning.
In a bathroom with decent natural light, Great Green gives you that leafy, spa-adjacent mood. Pair it with white tile and brass or matte gold hardware to lean into the warm olive undertone. Avoid pairing it with cool chrome, which can make it look muddier than you want.
This color can handle the main walls of a living room, especially if you balance it with lighter furniture and a warm white on the trim. It plays well with leather, jute, and natural linen. If your living room trends dark, consider it on just one or two walls.
If you are not ready to commit to green everywhere, Great Green makes a solid accent wall. It has enough saturation to read as intentional against a backdrop of warm whites or soft tans. Try it behind open shelving or a gallery wall for a grounded focal point.
What to Pair With Great Green
Divine White (SW 6105) is a warm, creamy white that lets the green in Great Green breathe without competing. Latte (SW 6108) adds a warm tan accent that draws out the olive undertone and grounds the palette even further. Together these three create a layered, organic scheme.

Colors that clash with Great Green
In rooms with limited natural light or under warm-only bulbs, the olive undertone can dominate and the color may read more brown-green than you expected.
Cool grays can pull out an unflattering yellowish cast from the olive undertone, making both the wall color and your furniture look off.
At an LRV of 42.9, Great Green absorbs a fair amount of light, and small bathrooms with one tiny window can feel closed in.
Common questions
Great Green has an LRV of 42.9, placing it right in the medium range. It reflects a moderate amount of light, making it versatile for rooms with average to good natural light.
It leans warm thanks to its olive undertone, but it is not strongly warm. In cool, north-facing light it can read greener and slightly cooler. Most people experience it as a warm-leaning neutral green.
A warm white like Divine White (SW 6105) is an excellent trim partner. It provides enough contrast without the harshness of a stark, cool white, which can make Great Green look yellowish by comparison.
