Irish Moss
What Irish Moss Actually Looks Like
Irish Moss is a rich, mid-to-deep forest green. It sits firmly in classic green territory, neither too blue nor too yellow, with enough depth that it reads as a true botanical shade rather than a pastel or muted sage. At this depth it absorbs a fair amount of light, so walls will feel enveloping rather than expansive.
Irish Moss Undertones
Based on its RGB values, Irish Moss leans slightly toward a natural, earthy green without strong blue or yellow pulls. It is a grounded, forest-floor kind of green. In lower light it can deepen toward near-black green. In bright natural light it opens up and reads more clearly as a lush mid-tone forest green.
Where Irish Moss Works Best
Because Irish Moss has a low light reflectance, it works best where you want drama and enclosure. Studies, libraries, dining rooms, and powder rooms are natural fits. It can anchor a large living room if you have generous natural light, but in a small, windowless room it will feel very close. Exterior trim and shutters are another strong use, where the depth reads as classic and grounded against siding.
Where to put Irish Moss
A deep green at this depth makes a dining room feel intimate and deliberate. Keep the ceiling lighter and use warm candlelight or incandescent bulbs, because cool LED lighting will push the color toward a flatter, cooler green.
Irish Moss is well suited to a book-lined study. The depth is serious without being harsh, and it makes wood shelving and leather seating look intentional. Make sure you have a strong reading lamp because this color will pull ambient light down.
Small square footage is no problem here. A powder room with no natural light can actually handle this depth well because you control the artificial light entirely. Warm bulbs and a well-lit mirror keep things from feeling like a cave.
Against white or cream siding, Irish Moss reads as a classic, heritage green exterior accent. It has enough saturation to hold up in full sun and enough depth to look intentional rather than flat.
What to Pair With Irish Moss
No specific coordinating colors are listed in our database for this color, so pair it by principle. Warm off-whites and creamy whites on trim keep the look fresh without fighting the green. Natural wood tones, brass hardware, and terracotta accents sit well against this depth. Black trim is a sharp, high-contrast option that lets the green do its work.

Colors that clash with Irish Moss
If Irish Moss is used in one room adjacent to a cool blue-gray, the two colors will fight rather than flow. The green reads earthy and warm by nature, and cool grays emphasize any yellow in it awkwardly.
Polished chrome and brushed nickel can look mismatched against this depth of green, emphasizing coolness that the color does not naturally support.
A very high-contrast bright white trim alongside this deep green in a dim room can feel jarring rather than crisp, making both colors look less intentional.
Common questions
The precise LRV is 16.51, which puts it firmly in dark territory. Colors below about 25 LRV absorb significantly more light than they reflect, so yes, this is a genuinely deep color that will make a room feel more enclosed.
It works on all four walls, but the room needs something to counterbalance the depth. Good natural light, a lighter ceiling, or lighter flooring will keep it from feeling oppressive. In a room with little natural light, an accent wall is the safer starting point.
Eggshell is the most practical choice for walls. It gives a slight sheen that helps reflect light back, which matters at this LRV, and it is washable. Flat will deepen the color further and make scuffs harder to clean. Satin works well on trim.
Yes, it is available in both Benjamin Moore interior and exterior formulations.
