What Color Is Back to Nature, Really?
Back to Nature (S340-4) is Behr's mid-tone sage green. The numbers tell you what your eye already senses: a yellow-leaning green hue softened to about 21 percent saturation, so it reads as a muted, gray-calmed sage rather than a fresh leaf green. With an LRV of 38 it sits almost exactly in the middle of the light scale, reflecting a bit over a third of the light that hits it. That means it holds real color on the wall without darkening a room.
Behr named it the 2020 Color of the Year, and it became the sage-green pick that went viral on Pinterest, which is why you still see it requested by name years later.
It suits people who want green that behaves like a neutral: farmhouse and cottage kitchens, calm bedrooms, and anyone pairing paint with wood, linen, and plants rather than bold color.
Back to Nature is unambiguously green, but the hue sits at 76 on the color wheel, on the yellow side of green. In practice that means it can flash slightly khaki or olive in warm afternoon light, while its gray softening keeps it from ever looking bright or grassy. Behr's own measurement calls it a cool green tone, and that is how it reads in shade and in north light: quieter, grayer, closer to a classic sage.
The yellow lean shows most next to true cool grays and blue-based whites, which can make it look slightly dingy by comparison. Test it against your trim white, your countertop, and any existing gray flooring before committing. Against warm woods like oak and walnut the undertone works with you, and the color settles into an easy, organic sage.
Best Rooms and Uses for Back to Nature
A 38 LRV is the versatile middle: dark enough to feel intentional, light enough to wrap a whole room without closing it in. That makes Back to Nature a legitimate four-wall color in bedrooms, living rooms, home offices, and entries, provided the room gets reasonable daylight. In a dim basement room it will read several steps darker than the chip.
It is one of the most popular sage choices for kitchen cabinets and bathroom vanities, where its muted saturation keeps painted cabinetry from feeling loud. It also works on a single accent wall behind a bed, on board-and-batten wainscoting below a light neutral, and on interior doors.
Outside, it performs as a full exterior body color on cottage and craftsman-style homes, paired with a bright white trim, and as a front door color on white, cream, or gray houses.
How Lighting Changes Back to Nature
At LRV 38, Back to Nature is a true mid-tone, and mid-tones shift more visibly with light than very light or very dark colors do. In a south-facing room with strong daylight, the yellow side of the hue wakes up and the color reads warmer, softer, and a touch more olive. In a north-facing room the gray in the mix takes over and it looks cooler, deeper, and more muted, sometimes closer to a gray-green than a sage.
East light gives you both versions in one day: warmer sage in the morning, grayer sage by afternoon. West rooms run the opposite direction.
Bulb choice matters as much as exposure. Warm bulbs around 2700K push it olive; cooler 3500K to 4000K bulbs keep it closer to its daytime sage. Look at your sample at night under the bulbs you actually own.
Most complaints about Back to Nature are a light mismatch. Upload a photo of your actual room and see it on your walls — then ask for the same wall in north light or evening lamps before you buy a single sample.
TEST IT IN YOUR LIGHT →Back to Nature vs Similar Colors
Within Behr's own deck, the closest neighbor is Willow Grove (PPU11-06), LRV 42. It is a step lighter and very slightly grayer, so it reads calmer in bright rooms; Back to Nature holds noticeably more color in the same light. If your room is small or dim, Willow Grove keeps things airier; if you want the sage to be clearly present, stay with Back to Nature.
Promenade (400F-5), LRV 41, is also a touch lighter but leans slightly greener and fresher, less khaki in warm light. Choose it when you want a hint more life in the green, and Back to Nature when you want a softer, dustier sage.
Sanctuary (PPU9-21), LRV 42, drifts further toward khaki and beige-green. It blends better with tan and beige finishes, while Back to Nature reads as the truer green of the two.
Colors That Go With Back to Nature
For trim and ceilings, use a soft warm white rather than a stark one. Behr Polar Bear (75), with an LRV of 86, is bright enough for crisp trim while its slight warmth agrees with the green. Swiss Coffee (12), LRV 80, is creamier and suits cabinets or walls in an adjoining room when you want the whole scheme to feel gentle.
For contrast, Cracked Pepper (PPU18-01), a soft black at LRV 5, makes a strong front door, island, or hardware-matching accent against sage walls. Dark Navy (PPU14-20), also LRV 5, does the same job in blue and is a natural partner for green.
If you want a second wall color elsewhere in the house, Smoke Blue (PPU14-10) at LRV 27 carries the same muted, gray-softened character in blue. Warm woods, aged brass, and matte black metals all sit comfortably alongside.

The Questions Everyone Asks
Is Behr Back to Nature warm or cool?
It sits close to the line. The hue leans toward the yellow side of green, which gives it warmth in strong daylight, but its gray softening makes it read as a cool, muted sage in shade and north light. Behr measures it as a cool green tone. Expect it to feel warmer in sunny rooms and cooler in dim ones.
What trim white goes with Back to Nature?
Behr Polar Bear (75) is the safest trim pairing. At LRV 86 it is bright enough to look crisp against the sage, but it has a slight warmth that keeps the contrast from feeling harsh. If you want a creamier, softer look, especially with painted cabinets, Behr Swiss Coffee (12) at LRV 80 is the gentler choice.
Does Back to Nature work on kitchen cabinets?
Yes, it is one of the most common sage cabinet colors. Its muted saturation keeps full cabinet runs from feeling loud, and its LRV of 38 gives enough depth to hide everyday wear better than a pale color. Pair it with a warm white like Polar Bear (75) on walls and brass or matte black hardware.
What does the LRV of 38 mean in practice?
LRV runs from 0 (black) to 100 (pure white), and 38 means Back to Nature reflects about 38 percent of the light hitting it. That is a true mid-tone: it will not brighten a room the way an off-white does, but it will not make one feel dark either. In low light it reads several steps deeper than the chip.
How is Back to Nature different from Sherwin-Williams Haven?
Sherwin-Williams Haven (SW 6437) is a very close match, with a measured color difference small enough that most people could not tell them apart on separate walls. Haven is marginally lighter at LRV 42 versus 38. If you are already buying Behr, there is no reason to color-match; the two are practically interchangeable.
How should I sample Back to Nature before painting?
Because it is a mid-tone that shifts visibly with light, paint two coats on a large board or a two-foot square in the actual room. Move it to each wall and look at it in morning light, afternoon light, and at night under your own bulbs. Check it directly against your trim white, flooring, and countertops before committing.
