Celtic Green
What Celtic Green Actually Looks Like
Celtic Green is a deep, saturated forest green. It reads as a true, full-bodied green with serious depth. Because its light reflectance value is very low, it absorbs a lot of light and can feel almost dramatic in how much it anchors a space. In bright direct sun it shows its richness most clearly. In dim rooms or north-facing light, it can read quite dark, closer to a deep forest shadow than a recognizable green.
Celtic Green Undertones
Celtic Green sits in cool-to-neutral green territory. It does not lean noticeably warm or yellow. The hex and RGB data confirm a blue-green lean, with blue and green working together to produce that deep, slightly cool forest character. Do not expect any olive or sage warmth here.
Where Celtic Green Works Best
Because Celtic Green is so dark, it works best where you want weight and presence. Front doors are a natural fit. It can ground a library, home office, or dining room. It reads well as a full room color in spaces with good artificial lighting or generous natural light, since low-LRV colors need some light to show their true character rather than just going flat and dark. Avoid it on ceilings unless you specifically want a cocooning, low-light effect.
Where to put Celtic Green
A deep forest green on a front door has a long history, and Celtic Green earns its place there. Pair it with brass hardware and a warm white trim for contrast that feels classic without being predictable.
Celtic Green on all four walls of a small home office or library creates a focused, enclosed feeling. Warm wood shelving and task lighting prevent it from feeling oppressive.
Dark dining rooms have a long tradition, and Celtic Green brings a nature-rooted seriousness that works especially well by candlelight or warm pendant fixtures. Keep trim light to give the eye a place to rest.
If you want the impact without committing the whole room, one Celtic Green wall behind a bed or sofa makes a strong statement. The depth of the color means even a single wall will shift the room's mood noticeably.

Colors that clash with Celtic Green
Celtic Green and cool blue-gray walls in adjacent rooms can feel tonally flat and cold together, since both colors pull in a cool direction without enough contrast to create interest.
Pairing Celtic Green walls with very dark trim in another deep color removes the contrast that makes dark wall colors readable and interesting.
In a room with little natural light and no strong artificial lighting, Celtic Green's very low LRV means it can swallow the room and feel oppressive rather than dramatic.
Common questions
Celtic Green has an LRV of 11.23, which is very low. Colors below about 15 LRV absorb most of the light that hits them, which is why this green feels so enveloping. It is not a color that will brighten a room. Plan your lighting accordingly.
Yes, Celtic Green 2038-10 is available in both Benjamin Moore interior and exterior lines, so you can use it on a front door in an exterior-rated finish or inside in whatever sheen level suits your surface.

Yes, noticeably. In a south-facing room with warm, bright light, you will see the true forest green richness. In a north-facing room with cool, indirect light, Celtic Green will read considerably darker and cooler, closer to a deep shadowed green. If your room is north-facing, test a large sample before committing.
