What Color Is Cool December, Really?

Cool December (DEC754) from Dunn-Edwards is a soft, light gray with a faint green cast. Its hex is #C7CCC4 and its LRV is 60, which puts it right in the middle of the light range: bright enough to open a room, but with enough body that walls do not read as stark white. The saturation is only about 7 percent, so the green almost never shouts. Most of the time it just reads as a calm, restful gray.

This color got national attention as the 2022 Dunn-Edwards Color of the Year, marketed as a coastal greige. That reputation is fair. It carries the airy, weathered feel of a beach house without leaning obviously blue or beige.

Cool December suits people who want a quiet, modern neutral that still feels warm and lived-in. It works in coastal and transitional homes, bright open plans, and any space where you want soft color instead of plain white.

On paper Cool December leans green. The hue sits at 98 degrees, which is squarely in the green range. But the saturation is only about 7 percent, so this is a near-neutral gray with a slight lean, not a true green. In most rooms you will read it as a soft, cool gray first and only catch the green in certain light.

The green shows up most next to warm materials. Put it beside oak, brass, or a beige rug and the cool cast becomes obvious. Put it beside crisp white trim or a cool stone and it settles down and reads gray.

To test it honestly, tape a large sample next to your trim white and near your flooring. Watch it in morning and evening light. If the green feels too strong, a warmer greige like Dover Cliffs (DEC771) will read calmer in the same room.

Best Rooms and Uses for Cool December

At LRV 60 this is a versatile, whole-room color rather than a statement shade. It has enough lightness to cover walls in bedrooms, living rooms, hallways, and open kitchens without making a space feel closed in, and enough softness to avoid the glare of a bright white.

It is a strong cabinet color for anyone who wants a quiet alternative to white kitchen cabinets. Its cool green lean reads as a gentle, modern gray on doors and looks natural next to wood counters and both brass and nickel hardware.

Outside, its coastal-greige character suits siding on beach and transitional homes, and it works on shutters or a garage door where you want tone without contrast. As trim it is usually too deep, since trim reads best a few steps lighter. Save the crisp whites in your palette for trim and let Cool December carry the larger surfaces.

How Lighting Changes Cool December

With an LRV of 60, Cool December bounces a good amount of light without turning glossy or clinical. That mid-to-light band makes it sensitive to the direction of your windows.

In north-facing rooms, which get cool, indirect light, the green and gray both deepen and the color can feel a little cooler and grayer. In south-facing rooms with strong, warm sun, it brightens and the green softens, often looking like a clean pale gray. East light in the morning is cool and can pull out the green, while west rooms warm up in the afternoon and calm it down.

Bulb choice matters just as much. Warm white bulbs around 2700K take the chill off and push it toward greige. Cooler bulbs at 4000K and up emphasize the gray-green and can make it feel sharper. Always judge a sample under the bulbs you actually own.

YOUR LIGHT IS THE RISKsame paint — south sun vs north grey

Most complaints about Cool December 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.

Cool December vs Similar Colors

Against So Chic! (DET614), which shares nearly the same LRV at 61, the two are close, but So Chic! reads a hair warmer and flatter while Cool December keeps its faint cool green lean. Choose Cool December when you want that touch of coolness, and So Chic! when you want a more neutral greige.

Silhouette (DE6276) is a bit deeper at LRV 56. On walls that extra depth is noticeable in lower light, so Silhouette can feel slightly heavier and more shadowed. Pick it if Cool December washes out in your bright room, and stay with Cool December if you want to hold onto lightness.

Dolphin Tales (DET600) at LRV 57 is a cooler, more purely gray version with less of the green cast. In a north-facing room Dolphin Tales can lean colder, while Cool December keeps a slightly softer, more coastal feel.

Colors That Go With Cool December

For trim and ceilings, pair it with a clean white that stays a few steps lighter. Whisper (DEW340), at LRV 84, gives a soft, bright trim without a hard blue edge, and Swiss Coffee (DEW342), also LRV 84, adds a slightly warmer, creamier frame if you want the room to feel cozier.

For a second wall color or an adjoining room, Dover Cliffs (DEC771) at LRV 67 is a touch lighter and warmer, keeping flow while adding subtle contrast. Forever Linen (DEC756) at LRV 60 sits at the same lightness but leans warmer, good for a connected space.

For accents and depth, Battleship Gray (DET636) at LRV 22 makes a grounded mid-tone for an island or built-ins, and Maiden Voyage (DEA178), a deep blue at LRV 8, is a strong front-door or accent-wall color. Warm woods and both brass and brushed nickel metals all sit comfortably against it.

The Questions Everyone Asks

Is Cool December warm or cool?

It is a cool color overall, but only gently. The hue technically leans green and the tone reads cool, yet the saturation is very low at about 7 percent, so it never looks strongly colored. In most rooms it comes across as a soft, calm gray with a faint cool cast rather than an obviously cool or icy paint.

Is Cool December more gray or more green?

More gray. The underlying hue sits in the green range, but with saturation near 7 percent the green stays very subtle. You will read Cool December as a light gray first and only notice the green in certain light or next to warm materials like oak or beige. It is a gray with a green whisper, not a green paint.

What trim white goes with Cool December?

Whisper (DEW340) is a reliable match. At LRV 84 it stays clearly brighter than the walls, so trim reads crisp without a harsh blue edge. If you want a warmer, softer frame, Swiss Coffee (DEW342), also LRV 84, is a creamier option that makes the room feel cozier while still separating cleanly from the wall color.

Does Cool December work on cabinets and exteriors?

Yes to both. On cabinets it gives a quiet, modern alternative to white and pairs well with wood counters and brass or nickel hardware. Outside, its coastal-greige character suits siding on beach and transitional homes and works on shutters or a garage door. As trim it is usually too deep, so keep trim a few shades lighter.

What does an LRV of 60 mean for Cool December?

LRV, or light reflectance value, runs from 0 (black) to 100 (pure white). At 60, Cool December reflects a good amount of light and reads as a light color, but it has more body than a bright white. That makes it versatile for whole rooms: it keeps spaces feeling open without the glare of a stark white wall.

How is Cool December different from So Chic!?

They are close in lightness, with Cool December at LRV 60 and So Chic! (DET614) at LRV 61. The practical difference is temperature. Cool December keeps a faint cool green lean, while So Chic! reads a touch warmer and more neutral. Choose Cool December for a slightly cooler feel and So Chic! for a warmer, plainer greige.
